Thanks for the update. I am a proud owner of the SE version of their preamp and that thing is awesome. I plan on getting this the moment it becomes available.

This one looks interesting. Small casing would fit perfectly for my needs. Waiting for the first impressions...

I'm looking forward to this. Rick does really nice work, and the price is about what a "level 3 mod" PS DLIII costs only with much higher quality parts. This could definitely be my new DAC.

Can someone refer me to a redbook CD that sounds better when upsampled to 192kHz, pls ? I'm not criticizing anyone's choices, but I'd like to try to hear the difference for myself. I own exactly one SACD, DIre Straits 'Brothers in Arms', and I rip everything to WAV using EAC, but I have yet to hear anything from the Topaz (Toslink from my MBP) that made me want to hear everything at 192 kHz - cloth ears, perhaps, but there you have it. I'm sure the SABRE is a better DAC - Topaz specs below for those wondering what I'm on about:

1) Main DAC : BURR-BROWN PCM1792
- 24 Bit 192 KHz Sampling Advanced-Segment Audio
Stereo DAC

- Dynamic Range : 123 dB / THD+N : 0.0005%

2) Digital Controller : Cirrus Logic CS8416
- 32KHzto 192Khz Sample frequency range
- Low Jitter Clock Recovery

3) USB Controller : BURR-BROWN PCM2707
- Full speed transceiver (Real Audio 1.1)
- 32Khz ~ 48Khz / 16bit delta-sigma stereo

4) OPAMP : TOTAL 8 pcs (DIP type)
- Output : Analog Device AD817 x 2 pcs
- I/V : Texas Instruments NE5534 x 4 pcs
- Headphone : Burr-Brown OPA2134 x 2 pcs

Its debatable whether or not upsampled material sounds better. FWIW I owned a Stello DA 220 which has a upsample bypass. I really could not hear a difference between 44.1 and 192. However, when I feed a upsampled signal to my Monarchy I do hear a difference and whether the difference is good or not depends upon the recording. The difference on the Monarchy is never large it is subtle but with the Monacry you are comparing 44.1 to 96khz which is not that big of a jump. I guess the W4S Dac represents the ultimate test of upsampling to me since it offers a direct comparison between 44.1khz and 500khz.


Focus more on the DAC design and DAC chip and less on the Upsampling or Oversampling stuff. I could be wrong but I think the main reason people are excited about this DAC is because it uses the Sabre DAC chip, its somewhat affordable and it is NOT DIY.

If you copy from SACD, you are copying regular redbook material, isn't it?

So, you probably won't hear much difference with upsampling and what not. If you listen to SACD player at native, it should be better, albeit small if engineered properly.

I think it depends on the software you use to rip the cd. I know you can rip the multichannel audio off of a DVD though so it stands to reason that one would be able to do so with SACD if the proper software is used. Plus you would need a cd rom that is capable of reading SACD.

I am just guessing here but if the DAC does not decode SACD it doesn't matter if he copied the SACD material or not, the DAC would just "read" the redbook material but that only happens if the SACD is hybrid and has a redbook layer.

Not to my knowledge. You can't rip the SACD as is from what I know. You can play through player and re-encode, if that's not same as ripping bit per bit.
post #24 of 76
Yeah, I have ripped audio from concert dvds a couple of times. I don't own any SACDs or a SACD player. I researched them a little when I was looking for a new player. In any event I agree with your first post seeing as I have a hard time differentiating between redbook and 192kz in some cases I know I couldn't tell the difference between SACD and 192khz.

If processed properly, there is no benefits above 16/44.1k. There is a huge discussion of this in Science forum. I suggest that you make a visit there.

There was a time when this thread would've piqued my interest. Now most DAC news I hear is a big snorefest. Blah blah low-jitter this, balanced that. Give me a good chip and good output stage first, please.
post #27 of 76
Thanks for the feedback guys, and the point was made early in the thread that its as much about implementation as the chip itself. As long as Marantz can make the Cirrus chip in my CDP do what its doing for me sonically, I don't give a hoot what the part number is. The twin Wolfson DACs in the CA 650C I auditioned send many reviewers into paroxysms of delight, but my ears made the choice that mattered.

atothex,

I'd say that this is an exciting time for DACs, with a number of designs coming out that employ the ESS Sabre DAC chips, which will allow us to compare and contrast the different implementations of these well-reviewed chips (in the DIY Buffalo DAC and Peachtree Nova designs). We've got Eastern Electric's swicthable tube & op-amp output stages, Wyred4Sound's discrete output stage (not to mention 24/196 USB input), as well as designs whose details haven't yet been disclosed from Peachtree (a standalone DAC) and Virtue . Not to mention non-Sabre chip designs such as the newly released AVA Vision DAC, which uses a new Wolfson chip and is getting a lot of positive reviews on the Audio Circle forums. Much excitement for those of us in the market for a DAC.

Definitely a good time for a DAC..
