Makes a pair of Klipsch R-26f sound great.

Unit sounds great and operates as intended. I use it exclusively with blue tooth and the range is good as I can have my phone in a different room and it continues fine. No problems in setup. All the clean volume I need with the 48v supply. I ordered on Nov 17 and paid extra for 3-7 day delivery. Unit arrived on Dec 3 so I was disappointed as I did not get much use before I departed the visit with my daughter on Dec 8. Hate to think how long it would have taken had I not purchased expedited shipping.

What can I say that hasn't? It's such a bargain that it's simply not smart not to have one. I have the BT20A and a V3 both with upgraded MUSE op-amps. Have my turntable hooked through a X2. I have the amps running through a Rockwell REQ42 EQ. I have a pair of B&Ws hooked to a Polk 12" sub through the BT20A and a pair of JVC SP7700s hooked to the other amp. Just nice, clean, detailed music that will simply amaze anyone with how it sounds.

After reading a very technical review of this amplifier, when an older amp had decided to replace it with this one, and it has functioned perfectly. Some time later, under similar circumstances, I bought another for a bedroom system. With the bluetooth I can have the amp. close to the speakers and feed it from across the room. This is perfect for my needs. The quality of the sound is excellent.
