Network Attached DAC?


I'm considering adding a PC based server into my system. The server will be big, noisy, and ugly enough to locate it somewhere in the basement, which, in turn, eliminates use of USB connection. I don't want to mess up with repeaters.

So, wired Ethernet is the way to go for me. Squeezebox seems to be the an obvious option. However before I make a decision I'd like to make sure I don't miss other, may be more audiophile-oriented options. If there are USB-enabled DACs, why wouldn't exist network attached DACs?..

Well, I would disagree with all three parts :)

USB never been a consumer format, and Ethernet with all due respect cannot be considered not as premium, nor as office oriented product, especially these days. USB will never replace Ethernet just because they are designed for totally different purposes. I agree that in consumer electronics Ethernet is still rare, which is, I guess, a matter of time.

As for using Squeezebox as a DAC,.. well you have Tri Vista DAC in your system, do you really believe in this option, to use Squeezebox instead ;) ?
Good.

So, getting back to the subject, there are few mass market options of getting the data over Ethernet and passing it via SPDIF: Squeezebox, Roku, XBox, some AV receivers. I know some can be modded, but...

There are few relatively hi end options, usually music servers with own hard drives, such as Olive music server, etc.

I'm looking for something in between: device up to audiophile level of requirements that can do just data => SPDIF conversion, or even better - combined with DAC.

Any ideas?

I love music, and I like audio. I think it's absolutely normal for Audiogon to ask about alternatives to seemingly obvious solution. I do not think arrogant tone is much helpful here. If you feel very much concerned about "ink", and if my question sounds boring or stupid to you, please feel free to simply ignore it.
Otherwise I would suggest that serious question deserves serious and respectful answer.

Now, back to business.

1. I'd prefer to eliminate SPDIF from the chain, and this is why did I ask about Ethernet enabled DAC. Well, ain't such a thing.

2. Although most of SB similar boxes may sound good, I don't believe they sound equal: they, at least, introduce different amount of jitter during data => SPDIF conversion

3. I cite: "In lesser systems the results are probably indistinguishable". May I ask if you can distinguish sonic signatures of two good CD players?

Well, may be I was unclear. Of course I2S is better, but in our reality it's virtually unavailable, let's take DIY and mods out of the scope.

What makes a difference is whether you have a separate converter connected to DAC through SPDIF only(!), or you managed to squeeze it into the same box, such as USB DAC. In the latter case, even if you use SPDIF internally, you have all the possibilities to embed a word clock link, thus eliminating the major drawback of SPDIF.
Just a short signal path in controlled environment makes jitter levels even lower.

So delivering the data straight to the dac makes life easier regardless of I2S availability.
Who said I want the ultimate? :) I never did. I want the optimal - quality, design, time, and money wise. At this moment mods don't fall into this category for me, sorry. Also, with correct design SPDIF can work pretty well, Benchmark DAC-1 is an example.

In the another thread I'm asking more general quesiton, and trying to get... well... alternative opinions. I respect yours, but I generally disagree with it.

Have you seen Mediabox MB-200? As it designed, its Audiophile edition should better Squeezebox by far. At this moment they're too buggy, but I guess this is just a matter of time.
