Suggestions For A DAC


I ask your for your wisdom and comments on finding a good used DAC. With all the new technology coming fast and furious, it seems like there are alot of good deals out there on used DACs. Some that I am considering Cal Audio Alpha, Muse Model 2, Adcom GDA 600/700, Bel Canto. Are tube units as good as SS? Also, is 96k upsampling worth it? I listen to mostly jazz and my budget is around $500-$800. My current system is: McIntosh MA6450 integrated amp, MCD7008 changer and Boston Acoustic A-150 speakers.

Thanks in advance.

I second the Bel Canto. I have seen used ones on Audiogon ranging between $600-$850. If you want to by-pass the preamp, go with the Birdland Oden Lite. There are discussions that can be found on this site regarding the Bel Canto, Birdland etc. They are both good and you can’t go wrong.
From my experience it's no worth to by modern tech upsampling DACs which most of the dealers are going to convince you. The ideal DAC has no upsampling! Upsampling sonically can enhance or deplete the sound but will never produce a linear real reproduction. Try to shop for Theta Cobalt, EAD DSP-7000 MKII. These are the best SS DACs that I've ever known for the today's price!
Since you listen primarily to jazz, i would shoot for the Alpha ( 16 bit ). Not only is this unit very reasonably priced, the liquidity of tube midrange on vocals is outstanding, the slight warmth and wetness of stand-up bass is untouched and treble shimmers without being harsh. This is besided the fact that you will now have air, depth and width to your soundstage that you didn't think possible. Should you feel the need, you can even alter the tonal and spatial characteristics via doing very simple tube swaps.

As others may note, tubes are for people that want to enjoy music and not necessarily "pick apart" or "dissect" recordings. Typically way more involving without the need to be analytical. The rest of your SS gear should supply the speed and impact that your looking for. Sean

Hi John. While I don't have any experience with most of the DACs you're considering, I do own the Bel Canto DAC1.1.

From what I understand, the original DAC1 and the newer 1.1 have some sonic differences. Choosing between these two may depend on the charactersitics of your current system. If you have an overly strident or lean system, the original DAC1 may be the better choice.

There have been a few people here that had their DAC1s upgraded to 1.1s and they remarked that it resulted in a quicker, more extended sound. For those that felt the original was too polite and dull, the upgrade was a welcome change.

I on the other hand had a system which was slightly lean. Adding the 1.1 extended the freqs. and both widened and deepened the soundstage without introducing any nasties. I'm very happy with this DAC. It's detailed without sounding unnatural.

This unit takes a long time to fully burn in. Around a month. However, used DAC1s are prevelant in the classifieds here for between $600 and $700, while the 1.1s are about $100-$150 higher.

Good luck and happy hunting!
