Another (grateful!) user looking for USB DAC advice

post #1 of 2
Thread Starter 

Hi all,

 

I'm looking for DAC suggestions as well as confirmation of my understanding of the technologies in my setup.

 

The DAC would ideally be small, as I would be (cheaply) bringing it back and forth between work and home occasionally.  My price range is approximately $200.  Here are my two setups:

 

Work:

Sennheiser HD650 headphones

Bottlehead Crack OTL amplifier

PC with ASUS Xonar DS soundcard (may be ignorable with the DAC)

 

Home:

Axiom M22 v3 main speakers

Outlaw LFM-1 Plus subwoofer

Yamaha HTR-6240BL 525-watt 5-channel receiver

Laptop or PC (laptop now, PC soon)

Sound Blaster X-Fi Surround 5.1 (USB) (may be ignorable with the DAC)

 

I'm thinking that a USB DAC would probably be preferable, since all my music is stored in FLAC format and I use my PCs to play them.  S/PDIF might be a nice-to-have feature as well.  I'm assuming standard composite cables would be my preferable output into my receiver at home and my Bottlehead amp at work.

 

Most of my music is standard CD-quality 16-bit, 44.1kHz FLACs, but I also have a lot of material in 24-bit, 48kHz and 96kHz FLAC as well.  It's important to me that I know for certain that what I'm outputting digitally is being processed and output in that format.  All the documentation on S/PDIF I can find is very iffy on this subject, so I'm beginning to think that tossing S/PDIF out the window might be a good idea in this case, and that I should utilize USB in both home and work scenarios.

 

What do you guys think?

 

Thanks in advance for your help.

Partly it is a hardware matter.

There are soundcards resampling everything to 48kHz

Likewise there are a lot of USB DACs limited to 16bit/48.

If playing audio at its native sample rate is important to you, you have to be careful in picking your hardware in both cases.

 

Partly it is a software matter.

Standard Win (or Mac) resamples everything to a rate set in the audio control panel.

In case of Win use a player supporting the WASAPI driver.

 

A (incomplete) list of 24/96 DAC’s can be found here: http://thewelltemperedcomputer.com/HW/USB_DAC.htm
