PerfectWave DAC / Zodiac Gold Shootout Round 1


I got about 250 hours on a Zodiac Gold + Voltikus and did a first round shootout against my PS Audio Perfectwave DAC + Bridge. Source for the Zodiac was Mac Mini over USB. The most level playing fiels setup I could think of was run the PS Audio single ended into the analog input of the Zodiac, match volume levels and run the Zodiac straight into my poweramp. This allows me to do A/B switching on the Zodiac input for a real time comparison.

I do have a Modwright 36.5 LS/PS that I use as a preamp with the Perfectwave, but for unbiased comparison of DACs only, I took this out of the chain alltogether.

Listening to acoustic, "small ensemble" music (mostly Jazz), the Zodiac had a slight edge. I little more air and transparency, but not by a big margin. If I did not own anything yet I would have probably bought the Zodiac and use is as a DAC/preamp.

However, the difference in SQ was small enough that I expect the forthcoming upgrade of the perfectwave dac (in a few weeks) to bring the Perfectwave to the level of the Zodiac. Additionally, I much prefer a network based architecture over USB and love the iPhone controller app (eLyrics) that controls the library for the perfectwave, so ease of use goes to PS audio.

I will do a second round listening session next week with 200 more hours on the Zodiac. I may also run both the Perfecetwave and the Zodiac through the Modwrigh and see what happens. However, as it stands right now the perfectwave stays.

Combined MSRP for a Perfectwave DAC + Bridge + Upgrade + Modwright 36.5 LS/PS is $15K (not including a few grand worth of cabling). You then have 3 chassis' and over 90lbs worth of components.

The Zodiac has the same functionality (if all you need is one analog input), for one third of the price, and is packaged in two small (10 lbs tops) boxes. Sound Quality is pretty close now - not sure what it will be like after the Perfectwav upgrade.

In summary, the Zodiac and perfectwave are both winners, and in a greenfield situation I suspect many would pick the Zodiac over the perfectwave. Those with a sunk investment in PS audio like myself will most likely stay with PS audio, especially now that a major upgrade has been announced.

What upgrade is planned to the pwdac? I ordered one 10 months ago and due to a speaker change has never been out of the box. Where can i read more? Thanks.
Thanks for the feedback. I'm not sure that running the PWD through the Zodiac Gold is a good way to compare them though.

You could run the PWD through the Modwright or directly into your amp. You couldn't A/B them this way but you could listen to each of them for a few days and see if you prefer one over the other.
James, if you go to page 6 of the PWD MKII thread on the discussion forum on the PS audio site, Paul explains in detail what this upgrade is about. Later on he adds that it will also add asynchronous USB and cost $1000 ($800 for early adopters).

Tom, the Zodiac is a full blown analog preamp, so when I run the PWD into the Zodiac I am usin the same preamp. Fair comparison IMO. However, I will probably try some other configuration - First, PWD and Zodiac both into Modwright. Than, PWD into Modwright active input and Zodiac into Modwright HT bypass. Both will allow A/B switching (unfortunately the Modwright cannot switch inputs with the remote). Personally, when differences are small I need to do A/B switching to make up my mind. Also, usually when differences are small I end up keeping the incumbent component.

I have already established in a different comparison I prefer the PWD through a preamp, so PWD direct will not be part of my configurations.
