Hi all. Just thought I'd bring to the attention the release of an intersting sub-$1k DAC. It's the Music Hall dac25.2 which I came across in the Stereophile CES blog. It has USB (amongst other) inputs, as well as RCA and XLR output (doubt it is fully balanced though). Even has a headphone out. Stereophile blurb:

Music Hall was showing a new USB DAC wit a tube output stage. The Music Hall dac25.2 ($600) uses an Electro-Harmonix 6922 tube, a Texas Instruments PCM1796 24-bi/192kHz DAC chip, a TI SRC4192 Asynchronous sample-rate converter (with a high-precision active crystal oscillator master clock), and four digital inputs (S/PDIF, TOSLINK, XLR, and USB). It sports re-clocking and user-adjustable upsampling (96kHz or 192kHz). It outputs analog via XLR or RCA.

To those of you who understand/know the various chips and components, kindly decipher the above to try help gauge if this might be the one

IIRC though, doesn't Music Hall rebrand their electronics from manufacturers in the Far East (not saying there is anything wrong with that)? Please correct me if I am wrong

. Also it seems the official CES page calls this the DAC 1.2

Cheers

Looks very nice. Would be one very interesting DAC when it's fully balanced though I guess I like a non-tube DAC.
Let's wait on those techies.

I had the fortune of listening to and checking this out while I was at ces. Very very nice piece, definitely some upgradability, as well as it using the i2s usb input with pcm 2704 chips. A very nice piece.

Music hall is simply the US distributor of shanling, at least thats my understanding...And I am pretty sure this is a unique design - at least I was unable to find a shanling DAC that is similar.

Any more impressions of this unit? Looks very interesting for the price. Anyone tried it out with HD6x0?

"I have compared the USB input to the Toslink/Coax inputs. Coax seems to be the best, but if you have stored your music in the most uncompressed format (AAIF or Apple lossless) than it's a very close race between the two. "

Not an impression, but at least something

Thanks.

We need more comments from people who have actually used this DAC/headphone amp.

SB Classic? Does that stand for "Sound Blaster"? If so, then I think there may be something wrong with your Music Hall if the Sound Blaster sounds better...

I hope it improves. Let us know how it goes.

Well the headphone amp is very simple in Music Hall. It can be that SB sounds better or someone just prefers the SB to the Music Hall. The DAC-section is what interest me more.

Yes I mean squeezebox. To my ears right now I think the dac in the Squeeze sounds more transparent. The music hall dac sounds congested and I think it might have to do with the tube output.

Does anyone know if the RCA or XLR outputs are variable?? Or is the Volume control only for the HP out?
