DAC/Pre's Digital attenuation vs. analog


Hello

I'm trying to decide whether to buy a W4S DAC2 and use the digital preamp, or to get the DAC1 with a separate component preamp (such as a Bryston BP25). I don't care all that much about the cost; just performance.

What are the advantages/disadvantages of going either way?

(I'm also considering a Benchmark HDR or USB).

"If I get your DAC but then have to control volume digitally on the Trinnov on the iPad (which is what I am doing now), I would not have the analog volume control benefit."

Yes, you could still get the benefit if you adjust the digital volume on the Trinnov to max and then set the manual volume on the Overdrive to a good listening level with your quietest track. Then, when a louder track comes on, just reduce the digital volume on the Trinnov 2-9dB. This will not impact SQ at all. You still have remote control.

Reading all the specs and tests in the world (on paper) about volume control will not tell you ANYTHING about how good a DAC will sound. Please stop this nonsense.
Not sure what the Benchmark unit costs, from who I have talked to, the W4S DAC-2 beats any of the Benchmark units. I really liked my DAC-2... was connected XLR direct into a BAT VK-55, sounded great. One small box does so much. They can price it that way b/c they do not sell at dealers. And like I mentioned... the resale is great if you decide to try something else. I also tried their big class D mono amps - not the same experience AT ALL. I guess I just prefer the tube sound, but I did not like any of those new amps with the B&O ICE modules... and I tried several.

I was using the DAC-2 off a netbook PC with mainly FLAC and WAX at 24/96 and some 24/192.

I got a great deal on a demo LINN Akurate DS (latest version) and it was quite an upgrade, so I sold my W4S unit.
Yes, just personal preference (although I have not personally owned the Benchmark, I am going off what others have said). I think the DAC-2 is a really great piece of gear. And if it were me, and I was only doing digital files, I would go without a preamp. If you have other sources (CD player, LP), then I suppose you would have to have at least a phono preamp. You could hook a CD player into the DAC-2 but this would make no sense... it would never sound as good as a hi-res file.
hi steve:

the problem is the digital volume control. when you set it to max, the analog vol control on the preamp is providing less gain.

my experience, as stated, is that is preferable to minimize the contribution of "digital" gain in favor of analog gain.
