Best Steely Dan Aja Vinyl Pressing: Original AB-1006 vs Cisco, MoFi, UMe and UHQR

Steely Dan’s Aja is easy to find on vinyl. Choosing the right pressing is considerably harder.

Collectors can choose between original 1977 ABC copies, the 1980 Mobile Fidelity edition, Japanese pressings, the respected 2007 Cisco reissue, the affordable 2023 Geffen/UMe LP and the premium Analogue Productions UHQR.

These editions can all sound impressive, but they do not present the album in the same way.

Quick verdict

Best overall sound: 2023 Analogue Productions UHQR
Best overall value: Clean 1977 ABC AB-1006
Best premium single-disc pressing: 2007 Cisco CLP-1006
Best affordable new copy: 2023 Geffen/UMe reissue
Best warm alternative: 1980 Japanese MCA VIM-4039
Most divisive pressing: 1980 Mobile Fidelity MFSL 1-033

The UHQR has the strongest support among the versions compared. Multiple reviews praise its quiet surfaces, deeper presentation, clearer separation and controlled bass.

A clean AB-1006 remains the more practical purchase for many collectors. It preserves the original one-record sequence, can sound natural and engaging, and usually costs far less than the premium editions.

Why Aja pressings inspire disagreement

Aja is often treated as a demonstration record, but its production is more complicated than simple clarity.

Chuck Rainey’s bass needs weight without covering the midrange. Michael McDonald’s stacked backing vocals on “Peg” should remain distinct. On the title track, Steve Gadd’s drums and Wayne Shorter’s saxophone need to sound connected while still occupying separate positions in the recording.

“Deacon Blues” presents another challenge. The song runs for more than seven minutes and closes side one on standard editions. The final section therefore sits close to the centre of the record, where cutting and playback become less forgiving.

The 45 RPM UHQR gives “Deacon Blues” an entire side. Some reviewers consider this one of its greatest advantages. Other listeners may still prefer the original album sequence without changing records after every one or two songs.

That tension runs through the available comparisons. The UHQR offers the strongest technical performance, while an early ABC copy offers value, authenticity and convenience.

Original 1977 ABC `AB-1006`

For most collectors, a clean AB-1006 is the best place to begin.

In his Analog Planet comparison, Mark Smotroff placed his original ABC copy behind the UHQR but ahead of the Cisco, Mobile Fidelity and standard 2023 UMe editions.

The original retained more excitement and musical involvement than most of the later alternatives. That makes it valuable for two reasons: it is close to the original release experience, and it remains competitive against far more expensive audiophile editions.

A strong original should sound balanced rather than obviously boosted. The bass has weight, but the vocals and keyboards remain present. The album’s precision does not erase the rhythmic energy underneath it.

What to look for

Do not identify the pressing from the cover alone.

The earliest US copies use the catalogue number AB-1006. ABC later changed the prefix to AA-1006 as part of a pricing-code revision.

Some transitional copies have AA labels or jackets but retain an altered AB-derived matrix in the runout. These may show an added letter or a crossed-out B.

Look for:

AB-1006 in the runout
evidence of an altered AB matrix
a clean playing surface
minimal groove wear
low noise near the end of side one

The deadwax is more useful than a seller simply calling a copy an “original pressing.”

`AB-1006` vs `AA-1006`

The difference between AB and AA copies is often oversimplified.

Some collectors describe every AB-1006 as excellent and every AA-1006 as inferior. The available comparisons do not support such an absolute rule.

Stereophile’s five-edition comparison used an original AA-1006 and still found it natural and musically convincing. The UHQR ultimately provided greater depth, sustain and separation, but the AA pressing was not treated as a poor record.

The additional complication is that ordinary AA cuts and AB-derived transitional copies are frequently grouped together.

A copy with an AA label but a modified AB runout may be closely related to the earlier version. Condition and the exact matrix can matter more than the letters printed on the jacket.

The safest advice is:

Prioritise a clean AB-derived copy, but do not reject every AA-labelled record without checking the runout.

2007 Cisco `CLP-1006`

The Cisco reissue was once the obvious premium recommendation.

It is an all-analogue, 33⅓ RPM edition mastered by Kevin Gray. Collectors frequently praise its quiet surfaces, clean detail and controlled tonal balance.

In a Polk Audio forum discussion, several participants favour Cisco, including one owner who directly prefers it to the older Mobile Fidelity pressing.

However, Cisco’s current resale price changes the calculation.

Analog Planet places Cisco below both the original ABC and the UHQR. The pressing remains detailed and refined, but the reviewer finds it less involving than the strongest alternatives.

That does not make Cisco unsuccessful. It remains the strongest premium option for someone who wants:

one 33⅓ RPM record
all-analogue mastering
quiet modern vinyl
a smoother presentation than some originals
no four-side 45 RPM interruption

Its main weakness is value. If a Cisco copy costs as much as or more than a new UHQR, the UHQR is easier to justify.

1980 Mobile Fidelity `MFSL 1-033`

The original Mobile Fidelity pressing is the most divisive major edition of Aja.

Stereophile hears a wide soundstage, airy upper frequencies and powerful bass. At the same time, the comparison finds the tonal extremes exaggerated.

That character can make the record sound large and exciting, but it may also reduce vocal weight and move the presentation away from the natural balance of a good ABC copy.

The Skeptical Audiophile reaches a much harsher conclusion. Its review criticises the pressing’s boosted bass and treble, thinner vocals and compressed presentation, ultimately preferring an ordinary vintage ABC pressing.

Collector opinion is less negative. In forum discussions, some owners continue to defend the MoFi and enjoy its dramatic low end.

The disagreement appears to be genuine rather than a matter of one side being objectively wrong.

Choose the MoFi when you already know that you enjoy:

strong bass emphasis
brighter upper frequencies
an unusually wide presentation
a more dramatic rather than neutral sound

It is not the safest version to buy blindly.

1980 Japanese MCA `VIM-4039`

Japanese pressings are often treated as one category, but the useful evidence here concerns the exact VIM-4039 compared by Stereophile.

That review describes the pressing as warm, sweet and easy to enjoy. It has generous presence and depth without the aggressive tonal extremes associated with the MoFi.

The trade-off is softer definition. Bass instruments can become less distinct, and the edition does not reveal as much fine detail as the UHQR.

Every Japanese pressing of Aja does not necessarily share this same sound. VIM-4039 is a specific alternative for listeners who prefer:

warmth
smoothness
relaxed vocals
a less analytical presentation

Collectors seeking maximum clarity and bass definition should look elsewhere.

2023 Geffen/UMe standard reissue

The standard 2023 LP is the easiest recommendation for someone who wants a clean, sealed and reasonably priced copy.

The record was cut from high-resolution digital files prepared from Bernie Grundman’s remaster.

Analog Planet’s dedicated review found the pressing quiet, centred and good value. However, the reviewer also heard some digital edge at higher volume.

The tested copy displayed possible end-of-side distortion and a brief channel dropout. These may have been isolated manufacturing problems rather than faults present on every copy.

Now Spinning offers a more enthusiastic view. Its review praises the edition’s warmth, bass response and low price.

That writer was mainly familiar with digital versions rather than vintage and premium vinyl pressings. That makes the UMe an enjoyable and affordable record, but not proof that it outperforms an original, Cisco or UHQR.

Buy the standard UMe when you want:

a new copy
low surface noise
easy availability
a sensible price
no need to inspect vintage deadwax

It is a strong entry-level purchase, not a budget version of the UHQR.

2023 Analogue Productions UHQR

The UHQR receives the strongest overall support.

Tracking Angle directly compares it with original AB and AA cuts, Cisco and Mobile Fidelity. The review considers the UHQR clearly superior, praising its bass extension, transient definition, decay and use of an entire side for “Deacon Blues.”

The edition was cut by Bernie Grundman through an all-analogue chain from an analogue tape copy because the original master is unavailable.

Analog Planet compared the UHQR with an original ABC, MoFi, Cisco and standard UMe copy. It ranked the UHQR first for its dimensional vocals, controlled bass, instrumental separation and musical involvement.

The same review still placed the original ABC in a strong second position. That makes the verdict more useful than an article that simply dismisses every older edition.

Stereophile reached a similar conclusion after comparing the UHQR with an original AA pressing, MoFi, Japanese VIM-4039 and standard UMe.

Its review praises the UHQR for:

very quiet vinyl
deeper spatial presentation
clearer instrumental placement
greater sustain
improved separation
a relaxed but focused sound

Audiophilia adds support for its clean bass, clear saxophone timbres, horn separation and stronger rhythmic movement.

Main strengths

quiet Clarity Vinyl
greater depth and separation
controlled low frequencies
clear vocal layering
reduced inner-groove compromise
strong agreement across independent comparisons

Main weaknesses

high price
four sides for a seven-song album
frequent record changes
large packaging
improvements may feel modest to owners of exceptional originals
source-tape descriptions are sometimes reported inconsistently

The UHQR is the strongest choice for listeners who place sound quality above price and convenience.

Original `AB-1006` vs UHQR

This is the central comparison.

Choose the original for

original one-LP sequencing
strong value
historical authenticity
natural tonal balance
fewer record changes
the possibility of finding an inexpensive copy

Choose the UHQR for

quieter surfaces
greater separation
deeper spatial presentation
stronger bass definition
clearer transient detail
reduced inner-groove compromise on “Deacon Blues”

The UHQR is the stronger technical presentation. The original is the better practical purchase.

A clean AB-1006 can still provide most of what makes Aja special without turning a seven-song album into an expensive four-side listening session.

What one Analoq listener noticed

Analoq currently has one community review tied to an identifiable 1977 US AB-1006.

The listener describes Aja as Steely Dan’s defining album and finds that “Deacon Blues” becomes more affecting with time. The exchange between Steve Gadd and Wayne Shorter on the title track is treated as one of the record’s central musical moments.

The review also provides useful identification advice by confirming AB-1006 in the runout.

Because this is one review, it is a firsthand owner observation that supports the broader case for the original as a musically satisfying and practical edition.

What the verified forum discussions suggest

The accessible collector discussions do not produce one unanimous ranking.

The older Polk Audio discussion contains support for Cisco, Mobile Fidelity and early ABC copies.

Cisco receives the strongest direct comparison, but several collectors remain satisfied with affordable AB-1006 or AB-derived transitional records.

A later Polk Audio thread gives the UHQR the clearest support. One participant prefers it slightly to Cisco, while another remains happy with an original AB-1006.

These discussions support two practical conclusions:

The UHQR is respected, but not every collector believes an upgrade is necessary.
Clean early originals remain attractive even after premium modern versions are considered.

Best Aja pressing by budget

Best lower-cost option: original `AB-1006`

A clean early ABC pressing offers the strongest combination of sound, original character and value. Exact runout identification and condition are essential.

Best affordable new option: 2023 UMe

Choose this when you want a sealed copy and do not want to inspect vintage records. It is good value, although not the strongest pressing overall.

Best premium single-disc option: Cisco

Cisco is an excellent choice for someone who values all-analogue mastering and the original one-disc sequence. Avoid paying more than UHQR prices.

Best premium option: UHQR

The UHQR offers the strongest verified sound quality. Its price and four-side format prevent it from being the default recommendation for everyone.

Best alternative presentation: Japanese `VIM-4039`

Choose it for warmth and smoothness rather than maximum resolution.

Most system-dependent option: Mobile Fidelity

The MoFi’s boosted tonal presentation may be exciting or distracting depending on the listener and playback system.

Final verdict

Based on the available comparisons, the 2023 Analogue Productions UHQR is the best-sounding vinyl edition of Aja.

Tracking Angle, Analog Planet and Stereophile all prefer it in direct comparisons, repeatedly praising its depth, separation, quiet surfaces, bass definition and use of 45 RPM groove space.

It is not automatically the best purchase.

For most collectors, a clean original ABC AB-1006 offers the best overall value. It preserves the album’s original flow, remains highly competitive and can cost far less than Cisco or UHQR.

The Cisco is the best premium single-disc option, but only when its price remains reasonable. The standard 2023 UMe is the best affordable new copy. The Japanese VIM-4039 provides a warmer alternative, while the MoFi remains too divisive to recommend without understanding its tonal character.

In practical terms:

Choose the AB-1006 for value and original character.
Choose the UHQR for maximum sound quality.
Choose Cisco for premium 33⅓ RPM playback.
Choose the UMe for affordability and convenience.
Choose the Japanese pressing for warmth.
Choose the MoFi only if you enjoy its exaggerated presentation.
