The exaSound DAC e22 Mark II ($3,500) has gotten great reviews but it is expensive and I prefer to buy from a USA Company. This unit is very interesting but I prefer not to have two boxes in my family room.
The Wyred 4 Sound DAC-2 DSD SE is very good but it is priced beyond what I want to pay ($2,765).
The NAD Master M51 DAC ($2,000) seems to be popular but I had problems getting pre-sale product information. If I have a problem with the M51 pre-sale info, getting after sale technical support could be a problem. In addition, I prefer a USA made product.
The Ayre QB-9 DC and the Ayre Cordex DAC are both excellent products but neither has the necessary optical and coaxial inputs I require. As I stated above, I am not willing to change my wiring connections to HDMI as required by the Ayre Codex. I am disappointed the Ayre DAC's do not have the two input connections I require.
The Benchmark DAC2 HGC has been highly recommended by friends and it looks excellent. It is made in the USA and priced at $1,999. The unit has four balanced 32-bit D/A converters that are summed together to create each balanced analog output. Does anyone have any comments on the Benchmark DAC2 HGC?

It seems I am changing my mind every week but this is based on new facts and product information. I am reading all the various posts and reviews I can find. Once I decide on a product, I will bring it into my system to see how it sounds. Thanks again for all your help.
