It is $7000 and available everywhere. You still need a DAC or DAC/streamer. The Peachtree Gan 1 is $1400 and all you need is a $400 IFI Zen Streamer and you probably have sound quality in the same league (or better)....than using the RS150B with the RS180 ($12K total). Of course, the streamer DAC and integraded amp have a LOT more features (but do you need them?). If you need more power there will be inexpensive amps available soon using the 400 watt a channel digital amp board from Elegant Audio Solutions (the 200 watt stereo board is what is in the GaN 1). GaNs are an improvement....but if you use a GaN based digital amp then you are another sonic step ahead.....and way cheaper, as you do not need a DAC, preamp, and analog interconnects. In five years you will see digital amps everywhere.....including inside speakers....this is the revolution many of us have been waiting for.....less stuff, better sound, less money spent.
