Apogee Mini DAC: Connection questions

hi dshea,
for some reason my mini dac sounds better with usb and optical (typical portable cd player) than spdif (dell laptop out, foobar resample to 48000Hz, vh audio pulsar with wbt nextgen copper). spdif gives a less focused sound. not night and day, but noticeable. usb and optical sound the same (identical song used).

Hi Tiberian,
I was hoping you were looking at these boards because you inspired me to get this amazing unit. Thanks for the tips on sound. Let me throw out a couple of other questions for you or anybody else.

I notice the sound out of the line out and heaphone jack are a bit different. The headphone jack has a little more highs and "reverberation" feel, where as the line out seems to be a little smoother and tighter. Do you notice any difference? I think I prefer the line out sound. My Zu mobius is getting refitted for balanced output so that will be my setup.

Also, I notice the sound is a little better with batteries than the cord, although there is nothing wrong with the cord sound at all. Does anybody use a specific power cord/conditioner, or are batteries the best for sound?

I love this unit. It is really amazing.

cheers,
dshea

dshea:

i just did a quick test with my headphones, i think the line out had a less next-to-your-ears feel plus a slightly clearer sound across the board than the headphones out (can be inaccurate, take it with a grain of salt). the line out can drive the sennheisers to louder-than-normal volume level as well.

i am using an aftermarket elpac medical power supply plus a running springs haley power conditioner with my mini dac (power cords are DIY vh audio flavor 4 with wattgate/furutech gold plugs). the elpac power supply gives a more holographic sound with better transparency than the stock.

i can be usually found around a'gon and a'asylum these days. never miss headfi, its fascist administration and site sponsored shilling one bit.

Hey Hugo,

Do you think it would be worth the upgrade to add the USB card connection. If there wouldn't be any major upgrade in sound quality, $195 may be a bit much to eliminate my Waveterminal U24 from the chain. It is connected to the DAC with a glass toslink.

Are you using an amp with your unit? or are you still using a balanced Zu connected directly to the XLR jacks?

I continue to be intrigued by the different sounds coming from the headphone out and line out. Some things sound a little better to me with the more "wet" sounding trebles from the headphone out, but most things seem to sound a bit better from the fuller and more detailed bass and mids from the line out. It is like having two different setups, both sound excellent.

When I get my Zu back I suspect that is what I will settle on.

cheers,
dshea

i am using a dynahi with my mini-dac, a properly built dynahi sounds way better than driving the 650s with the balanced out.

skip the usb option if you don't really need to use it with your computer.
