COMPLETE REEL-TO-REEL MASTER TAPE CATALOGUE 2026

OPENREELTOREEL HUB WORLD COLLECTOR’S REFERENCE

Complete A–Z Master Tape Database

🇮🇹 AudioNautes Recordings — Italy

For serious reel-to-reel collectors, AudioNautes occupies a fascinating position in today’s master-tape market: historic analogue recordings, modern recordings, original session/master sources and high-speed one-to-one duplication coexist in the same catalogue.

AudioNautes states that it works with original master sources — analogue tapes, files, tapes or DAT — rather than automatically using later remasters, and describes its remastering philosophy as deliberately purist and minimally interventionist. 

The current official Reel-to-Reel catalogue contains 13 releases.

Collector verdict: A cornerstone title for a world-class reel-to-reel collection.

 

🎷 ARNE DOMNÉRUS & ASSOCIATES

JAZZ AT THE PAWNSHOP VOL. 2

Catalogue: AN RTR 2304
Format: 2 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM SM900

OpenReelToReel Rating: ⭐⭐⭐⭐⭐ 5/5 — REFERENCE

AudioNautes states that it obtained the original session tapes from Proprius, retained their original balances and produced the release entirely in the analogue domain. 

Collector verdict: Arguably one of the most interesting Pawnshop editions because it exposes material very close to the original sessions.

 

B

🎼 BENGT BERG / STORKYRKANS KÖR

NOW THE GREEN BLADE RISETH

Catalogue: AN RTR 2303
Format: 2 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM SM900
Duplication: 1:1
Machine chain: Otari MTR-15 → Otari MTR-15
Source: Original master tapes
Provenance: AAA / full analogue
Edition: Sequential numbering from #001
Packaging: Booklet + signed certificate

AudioNautes explicitly describes the release as being produced from the original master tapes through a full-analogue AAA process. 

The label also notes its close relationship to Cantate Domino: same choir, conductor and recording engineer. 

 

G

🎹 GLENN GOULD

J.S. BACH — GOLDBERG VARIATIONS, 1955 MONO

Catalogue: AN RTR 2607
Format: 1 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM LPR90
Recording: Mono
Duplication: 1:1
Machine chain: Otari MTR-15 → Otari MTR-15
Edition: Sequentially numbered from #001; number applied to metal reel
Packaging: 4-page leaflet
Original recording: Columbia, June 1955
Original engineering: Fred Plaut associated with the session
Genre: Classical / Solo Piano
Price: €750–€1,000
OpenReelToReel Rating: ⭐⭐⭐⭐⭐ 5/5 — HISTORICAL REFERENCE

The AudioNautes page confirms a single ¼″ LPR90 tape at 15 ips and the one-by-one Otari duplication chain. It describes Gould’s historic June 10–16, 1955 Columbia sessions, but the current product page does not explicitly declare AAA/ADA provenance, so this database deliberately does not manufacture a provenance code. 

Collector verdict: Extraordinary historical importance and probably one of the catalogue’s most desirable mono releases.

H

🎤 HARRY BELAFONTE

BELAFONTE AT CARNEGIE HALL

Catalogue: AN RTR 2305
Format: 3 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM SM900
Duplication: 1:1
Machine chain: Otari MTR-15 → Otari MTR-15
Source: RCA 1959 stereo downmix tape
Provenance: AAA / full analogue
Edition: Sequentially numbered from #001
Packaging: Booklet + signed certificate
Genre: Vocal / Folk / World / Live
Price: €1,769
OpenReelToReel Rating: ⭐⭐⭐⭐⭐ 5/5

AudioNautes states that its remaster starts from an RCA stereo downmix tape from 1959 and that the process remains fully analogue, AAA. 

Collector verdict: A monumental live recording presented as a serious three-reel analogue edition.

🎻 GREGORIO PANIAGUA / ATRIUM MUSICAE DE MADRID

LA SPAGNA — XV, XVI & XVII CENTURIES

Catalogue: AN RTR 2205
Format: 2 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM SM900
Duplication: 1:1
Machine chain: Otari MTR-15 → Otari MTR-15
Source: Original session tapes
Provenance: AAA / full analogue
Edition: Numbered
Packaging: Booklet + signed certificate
Production status: No longer in production
Genre: Early Music / Classical
Current remaining-price indication: €1,350–€1,390
OpenReelToReel Rating: ⭐⭐⭐⭐⭐ 5/5 — COLLECTOR PRIORITY

AudioNautes confirms full analogue AAA production, and states that the tape was made from the original session tapes; the edition is now officially described as no longer in production. 

Collector verdict: The discontinued status materially increases its long-term collector appeal.

 

N

🎤 NAT KING COLE

PENTHOUSE SERENADE

Catalogue: AN-RTR-2603
Format: 1 × Reel Tape
Tape stock: RTM LPR90
Available versions: Mono / Duophonic
Tape width: Current AudioNautes page does not explicitly specify
Speed: Current AudioNautes page does not explicitly specify
Source/master provenance: Not explicitly disclosed on current product page
Genre: Vocal Jazz / Easy Listening / Piano
Price: €750
OpenReelToReel Rating: ⭐⭐⭐⭐½ 4.5/5

The current official listing confirms a single RTM LPR90 tape and offers Mono and Duophonic variants. 

Collector verdict: Highly desirable musically, but the current product listing needs fuller source-chain documentation before it can earn the database’s maximum provenance score.

O

🎼 OSCAR’S MOTET CHOIR

CANTATE DOMINO

Catalogue: AN-RTR-2107
Format: 2 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM SM900
Duplication: 1:1
Machine chain: Otari MTR-15 → Otari MTR-15
Edition: Numbered sequentially from #001
Packaging: Booklet + signed certificate
Genre: Choral / Sacred / Classical / Audiophile
Price: €1,159
OpenReelToReel Rating: ⭐⭐⭐⭐⭐ 5/5 — AUDIOPHILE REFERENCE

The official page confirms two ¼″ SM900 tapes at 15 ips and one-by-one Otari duplication. AudioNautes’ separate technical discussion identifies Cantate Domino as an example where the original master itself reflects editing/assembly of session material, illustrating why “original master” and “session tape” should not automatically be treated as identical concepts. 

Collector verdict: One of the classic Scandinavian audiophile recordings and an obvious anchor title for the catalogue.

 

T

🎹 TSUYOSHI YAMAMOTO TRIO

BLUES FOR K

Catalogue: AN-RTR-2606
Format: 2 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM SM900
Duplication: 1:1
Machine chain: Otari MTR-15 → Otari MTR-15
Recording date: 20 June 2022
Recording engineer: Yoshihiko Kannari
Original master: Digital
Provenance: DAA
Edition: Sequentially numbered
Packaging: Booklet + signed certificate
Genre: Jazz / Piano Trio
Price: €1,220–€1,550 currently displayed
OpenReelToReel Rating: ⭐⭐⭐⭐½ 4.5/5

AudioNautes explicitly states that Kannari’s June 2022 original master is digital, and therefore classifies its production chain as DAA rather than AAA. 

Collector verdict: Excellent modern jazz tape and admirably transparent provenance — but not an AAA recording.

 

🎹 TSUYOSHI YAMAMOTO TRIO

PLAYS SONGS

Catalogue: AN-RTR-2621
Format: 2 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM SM900
Duplication: 1:1
Machine chain: Otari MTR-15 → Otari MTR-15
Original recording: March 2026
Recording engineer: Yoshihiko Kannari
Original master: ½″ analogue master tape
Standard release source: Original ½″ masters
Optional format: ½″ version available on demand
Publication: Scheduled October 2026
Price: €1,220
Genre: Jazz / Piano Trio
OpenReelToReel Rating: ⭐⭐⭐⭐⭐ 5/5 — FUTURE REFERENCE

⚠️ PROVENANCE NOTE: The current AudioNautes page contains an internal terminology inconsistency. At the top it says “From the original 1/2″ master tapes – AAA”, while the description later calls the March 2026 ½″ tape master “AAD.” Because the physical source is explicitly described as ½″ tape, OpenReelToReel records the source as analogue ½″ master while flagging the AAA/AAD coding for clarification rather than silently choosing one. 

Collector verdict: Potentially one of AudioNautes’ most important new releases — especially the special ½″ edition.

 

V

🎻 ANTONIO VIVALDI

LE QUATTRO STAGIONI — THE FOUR SEASONS

Catalogue: AN-RTR-2605
Format: 2 × Reel Tape
Tape width: ¼″
Speed: 15 ips
Tape stock: RTM SM900
Duplication: 1:1
Machine chain: Otari MTR-15 → Otari MTR-15
Original recording: March 1992
Recording/master associated with: Michael Seberich
Original master: Digital
Provenance: DAA
Programme: Four Seasons + three RV286 bonus movements
Edition: Sequentially numbered
Packaging: Booklet + signed certificate
Genre: Classical / Baroque
Price: €1,159–€1,600
OpenReelToReel Rating: ⭐⭐⭐⭐½ 4.5/5

AudioNautes explicitly identifies the March 1992 original master as digital, hence its DAA designation. 

Collector verdict: A premium tape edition whose value rests on mastering, duplication and musical performance rather than an AAA claim.

 

V / VARIOUS ARTISTS

🎞️ AUDIONAUTES RECORDINGS

15TH ANNIVERSARY LIMITED EDITION

Catalogue: AN RTR 2408
Edition: 15th Anniversary Limited Edition
Numbering: Regular / non-serial-number option currently shown
Tape configuration: Not disclosed on current product page
Tape stock: Not disclosed
Speed: Not disclosed
Source: Not disclosed
Provenance: Not disclosed
Genre: Audiophile / Compilation
Current status: Sold out on catalogue page
OpenReelToReel Rating: ⭐⭐⭐⭐☆ 4/5 — COLLECTOR EDITION

AudioNautes currently lists the release in its Reel-to-Reel catalogue but the present product page contains almost no technical documentation beyond the edition information. 

Collector verdict: Potentially very collectible because of the anniversary connection, but the technical database should remain conservative until AudioNautes publishes or confirms the complete tape specification.

🏆 OPENREELTOREEL HUB - THE ESSENTIAL FIVE

If building an AudioNautes reference collection, our five priority titles would be:

🥇 Jazz at the Pawnshop — AN RTR 2203
⭐⭐⭐⭐⭐

🥈 Jazz at the Pawnshop Vol. 2 — AN RTR 2304
⭐⭐⭐⭐⭐

🥉 Antiphone Blues — AN RTR 2204
⭐⭐⭐⭐⭐

🏅 La Spagna — AN RTR 2205
⭐⭐⭐⭐⭐ — especially significant now that production has ended.

🏅 Cantate Domino — AN-RTR-2107
⭐⭐⭐⭐⭐

Special historical choice:
🎹 Glenn Gould — Goldberg Variations, 1955 Mono — AN RTR 2607 ⭐⭐⭐⭐⭐

New-generation choice:
🎹 Tsuyoshi Yamamoto Trio — Plays Songs — AN-RTR-2621 ⭐⭐⭐⭐⭐

 

🎞️ TECHNICAL SUMMARY

VERIFIED 15 IPS / ¼″ / RTM SM900 TITLES

• Cantate Domino
• Antiphone Blues
• La Spagna
• Now the Green Blade Riseth
• Jazz at the Pawnshop Vol. 2
• Belafonte at Carnegie Hall
• Vivaldi — Four Seasons
• Yamamoto Trio — Blues for K
• Yamamoto Trio — Plays Songs

The original Jazz at the Pawnshop AN RTR 2203 is also documented by specialist retail listings as a 4-reel, ¼″, 15-ips SM900 edition. 

RTM LPR90

• Glenn Gould — Goldberg Variations: 1 × ¼″ / 15 ips LPR90 
• Nat King Cole — Penthouse Serenade: 1 × LPR90; Mono or Duophonic variants 

 

🔴 AAA — VERIFIED BY AUDIONAUTES

✅ Antiphone Blues
✅ La Spagna
✅ Now the Green Blade Riseth
✅ Jazz at the Pawnshop Vol. 2
✅ Belafonte at Carnegie Hall

Plays Songs is explicitly described at the top of its product page as sourced from original ½″ master tapes and “AAA,” although the same page later says “AAD”; that discrepancy should be clarified by AudioNautes. 

🔵 DIGITAL ORIGINAL MASTER / DAA

🔹 Vivaldi — Four Seasons — DAA
🔹 Tsuyoshi Yamamoto Trio — Blues for K — DAA 

This distinction matters.

A premium reel-to-reel tape does not automatically mean AAA.

AudioNautes deserves credit for identifying digital-master recordings as digital-origin rather than disguising them behind vague “master tape” terminology.

 

⚙️ THE AUDIONAUTES DUPLICATION STANDARD

Across many current editions AudioNautes specifies:

🎞 ¼-inch tape
⚡ 15 ips / 38 cm/s
🎚 RTM SM900
🔄 One-by-one duplication
⚙️ Otari MTR-15 → Otari MTR-15
📜 Signed certificate
🔢 Sequential numbering from #001

That combination places these releases firmly in the modern premium open-reel collector market. 

 

⚠️ COLLECTOR AUTHENTICITY NOTES

AudioNautes says its genuine Reel-to-Reel products are original, signed, registered and sequentially numbered, and that it keeps a record of where individual numbers were sold.

The company currently warns specifically against products carrying the AudioNautes name offered by SmartAudioeu and mirrored on Buyee.jp, which it describes as fake. 

For high-value master tapes, provenance is part of the collectible.

🎧 OPENREELTOREEL HUB COLLECTOR VERDICT

AudioNautes Recordings Master Reel Tape Copy Catalogue 2026

Recording catalogue: ⭐⭐⭐⭐⭐
Master-source access: ⭐⭐⭐⭐⭐
Analogue heritage: ⭐⭐⭐⭐⭐
Duplication quality: ⭐⭐⭐⭐⭐
Presentation: ⭐⭐⭐⭐⭐
Historical importance: ⭐⭐⭐⭐⭐
Catalogue diversity: ⭐⭐⭐⭐½
Technical transparency: ⭐⭐⭐⭐½
Collector desirability: ⭐⭐⭐⭐⭐

OVERALL OPENREELTOREEL HUB RATING:

⭐⭐⭐⭐⭐ 4.9/5

AudioNautes Recordings is not simply issuing music on tape.

At its best, the catalogue combines important historic recordings, original master/session sources, professional high-speed tape formats, premium RTM stock and individually produced collector editions.

And importantly, when the original master is digital, AudioNautes sometimes says so.

For serious collectors, that transparency matters almost as much as the tape itself.
