Tascam DA-3000

DhI93449,
The largest file that this unit will create during record is
2GB. If a recording is about to exceed this size, a new file is
automatically created, but the audio is processed so there
is seamless continuity between the current and new file. On
playback, in order to hear the audio seamlessly, please set
the TRACK GAP mode setting to “GAPLESS”.
(See “Setting
gapless playback mode” on page 41.)

Is this solution to the 2GB limitation:

GAPLESS
is selected during DSD file playback
Depending on the status of the audio data, noise might
occur at the division between tracks due to the nature
of DSD files. If the noise is bothersome, set the track gap
mode to
NORMAL
to avoid it. (Noise will not occur during
the gapless playback of audio from tracks created using
this unit’s auto track and track increment functions, for
example.)

Topten:

I realize that, and was responding to your question about the use of a "CD" recorder for capturing vinyl LPs. CD media is limited to 700 MB. By CD recorder I am assuming you mean recorders that directly write to CD media.

Since most LPs are limited to < 20-25 minutes per side, you will only exceed this for a single 2 GB file for DSDIFF at the 5.6 MHz sampling rate! This is way overkill for LP recording, especially with IC opamp buffers in the input circuitry (they will limit the sound quality, not the digital capture conditions).

In fact, with 2 GB, you can record a 26 min .WAV file at 24bit, 192KHz. Since the longest single, uninterrupted song on a LP is usually under 20 min, there is no need to worry about splicing files larger than 2 GB together.

Also, those instructions are only for playback on the Tascam. I would convert the .WAV files to FLAC for playback on my music server and would never use the TASCAM for anything but the original A/D conversion.

Dhl93449 - there is an Ayre QB-9 listed for sale here. The B is the successor to the Ayre with DSD, but opnly does 88 MHz DSD.

There is a Korg MR2000 available here for $900. Busman does mods to those. They did mine and the recordings at 24/192 are very comparable to my turntable. The Korg records to a disk but than you can transfer to a PC via USB. That unit is no longer made, but was a "low end" professional unit.

The QB-9 is the D/A. The QA-9 is the A/D.

I have yet to see a QA-9 for sale. I went ahead and bought a TASCAM 3000 on fleabay for $720 new. For that price I can afford to try some op amp mods. I think I can remove the 5532s and replace with OPA627s on a Brown Dog adapter. For my purposes, only the input buffer amps need to subbed out. Once I have the digital file, it will be played back in my Bryston BDP/BDA combo which uses Class A discrete analog stages.

If in the future a QA-9 becomes available, I'll consider it at that time, depending on the results I get with the Tascam.

Opps, my mistake.

Did you look at the old Korg or the new DS-DAC-10R?
