DAC Under $3000

I did get a the CEC DAC DS5 directly from Japan for $1,500 and it is a superb DAC

Plays DSD but not SACD.

Note,  it is a 110 volts I did get a transformer for it, even though some experts sat it does not  matter. Our “120” is seldom 120, right now my power regulator  indicates   115

In USA the same CEC DAC goes goes $3,000 and in Europe for more than 3,000 euros!

Good luck on your search.

Some Ayre DACs only support USB… but others support SP/DIF, optical, and AES. It depends on the model.

Both the new QX-8 and QX-5 support multiple digital inputs but they are not within his $3,000 budget.

I don't have any experience comparing external DACs in my system, but, based on how my set up compares to my analogue source, the Black Ice Tube DAC at $800 + $450 NOS Mullard tubes is really impressive.
