Might be computer generated interference, but most probably it's ASIO... So try listening without ASIO for a while and see if the problem occurs then. (I can certainly say that the Otachan build for foobar 0.8 I'm using is certainly not "bug-free" either.)

Yes, I think they posted the compass's in batches according to voltage.

EDIT: Just a guess here... but the Compass hissing wouldn't be due to grounding problems right? Would the Compass have grounding problems?

Grounding problems usually show up as a consistant hum or similar. As I understand it, the Compass has some protection against that. Intermittent weird sounds are more than likely your computer or interference somewhere.

But back on topic: a DAC makes a sound card obsolete right? Or will it be wise to buy an additional x-fi titanium for example?
Also; somebody here has their speakers for sale. He says they output 95db @ 1.5w (or something). That got me thinking: audio-gd has this beautiful poweramp for sale to go with the compass; but is it necessary for speakers like that? You can theoretically hang efficient passive speakers on the pre-amp out right?



I only know so much about speakers and the like, but you have to watch out when hooking up speaks to something not powerful enough to drive them as you could fry your Compass. I would expect that the safest thing to do would be to just go with the Panther or another power amp.

Peete.



Well, I have some exams to write this coming week (I start tuesday, finish the tuesday after that) and it would probably be better for my studying if it came later... NAH ASAP WORKS FOR ME!

I still have a hard time believing that it can ship from China that quickly!

I'd say good headphones between $150-300 if you only have compass and stock everything else, more detailed headphones if you plan to upgrade things like power and headphone cable. Then you might consider some of the higher end stuff like the C-2c or Dac19. My new headphones has shown me that it's actually bad to upgrade to a too revealing headphone if other things aren't up to par (modding the headphones fixes that, but I'm stubborn :/).

What I mean is I think high end gear is more sensitive to noise in cables than other stuff, I actually find crap source sounding better than expensive source when I take away custom power but retain headphone cable, or find expensive source sounding better by taking away all rather than everything but keeping the headphone cable. Then there's also the issue of the quality of what you listen to, it's unbearable to listen to 128kbps cbr with my best setup while very enjoyable when I take many parts out.

Probably your computer. But it could also be the hdam is not seated well in the socket. Sometimes if it isnt making contact you will get an intermitant hissing with certain freq. also make sure ground to hdam is secure.

This is a tiny bit tricky. You still need a transport - coax optical or USB... IMO the best thing to do it try your built-in sound card's digital out, if you get noise or are not satisfied, try USB, and then if you still aren't happy (or need 24-bit 96khz playback like for DVD-A or SACD) THEN try a dedicated sound card like an x-fi. I have a sound card for the gaming features, but in testing the coax out from my onboard sound card I got a lot of "static"... so I use the coax out of my xfi.

If you buy that Poweramp you mentioned, you'll be able to run "un-amplified" spkrs fine. If the spkrs you are looking at are amped, you can run them from the Compass.

Does having the preamp switch in the front alter SQ in any way?

^^ I heard that they were shipping more out on Sunday, plus batch 1 and 2 already gone, then I think its just the later orders to complete and ship.

I ended up leaving my Compass at work, powered on for the four day weekend. With all the festivities and family coming over, I wouldn't have been able to listen but I still want to run some comparative tests before I start writing my review. I have looked for a unit like the Compass for years, particularly with an internal bypass for the amp section. I'm very enthusiastic about all the products coming out that are making desktop listening such a joy.
