Just a short update. My original unit had a defective headphone jack, did not cut out the speakers when plug put in headphone jack, I contacted Monoprice and got a RMA and sent it back for free shipping and got another unit in a couple of days and the new one works great. So good customer service.
I had the integrated amp trying to push my office system with very inefficient 83db at one watt DIY Core 2's tower speakers. Had to turn up the volume to three quarters to get loud enough for hard rock and could tell that the unit was straining to deliver enough power. Although Monoprice states it's 25 watt output per channel. The instruction manual states that the RMS rating is 15 watts per channel. So I ended up putting the Monoprice amp in my garage system with my B&W Matrix Two. It sounds great and drives the speakers well. I had got hooked on the "tube" sound from listening to the Monoprice and went out and got a Little Dot MK III tube preamp/headphone amp for $200 on eBay and I am using a EMO UPA-200 to drive the system. Sounds very good. Might upgrade the tubes on the Little Dot in the future.
I have to say that I am impressed with the sounds quality of the Monoprice hybrid Tube amp, especially with high sensitivity speakers. Perfect for small office systems or dorm rooms.
