Rega DAC ...what else should I consider ?

Burson conductor, it also have a beefy headphone amp.

Hegel HD11

The new Bryston Dac-II is supposed to be the cat's pajammas

May want to give the Emotiva DAC a look. The are direct sales outfit.

You should be able to get a Teac 501 from Music Direct.

Inexpensive maybe the new DragonFly or MyDac. Also the Arcam RDac--very musical. I own an RDac and use it downstairs.

For my upstairs system, I just compared the Benchmark HGC-2 and the NAD M51. I liked the Benchmark but I love the NAD M51. And I can connect my Oppo blu-ray via HDMI and play SACD and DVDA thru the NAD and it sounds fantastic.

Doggiehowser,
Can you direct where to purchase TEAC 501?

Here's the review I mentioned.

NAD M51. Not enough superlatives.

I should have added I picked the Rega was that I already have an Apollo R and RP1.

How much is the Rega?

For my money, the new TEAC UD-501 is hard to beat.

It has dual coax, dual Toslink and a USB input that supports up to 32bit/384kHz AND 2xDSD!

Supports both XLR and RCA outputs. Uses dual balanced mono architecture and TI BB1795 DACs.

Also has a decent headphone amp.

A good review of it is in the Stereophile sister site (audiostream)
