AGD Duet Monoblocks

@aw-agd 

your comment is appreciated. I’ll make it a point to stop back by at CAF26.

AGD Duet owner here since last summer and they work great with the DeVore Super Nine speakers!  I've owned a number of amps over the years and the Duets have brought out the best in the DeVore's.  First time I have ever used mono blocks (due to space issues, etc.) which have made me a believer in that design. (Okay, and they are the most expensive amps I have ever used. :) 

They are also compact in size, put out plenty of power and have both RCA andXLR inputs. I run my streamer/internet tuner directly into the RCA inputs of the amps, which allows me to bypass my tube based preamp, thereby saving tube life.

The clincher though is that the amps are upgradeable by the owner which will save  time and money. While there are other fine GaNFET amps out there, AGD is the only company I am aware of that offers this feature which is important (to me) since the technology is still relatively young.

@bartsw Thanks for the additional advice about their being desktop amps. Makes sense. I suppose, that I’m impressed in them sounding this good regardless, but your point is important. The fact they *can* sound this good, with the level of cheap construction you’re suggesting, does seem proof of concept of something.

After all, the Fosi V3 with the power supplies and the op amps is about 17x less expensive. Obviously they are built to a price point and may not last 20 years, but if one had to buy another set in 5 years, they would still far cheaper than say the other models.

P.S. I think we'd agree, too that there are plenty of real audiophile amps without protection circuits that will happily kill speakers. I don't know if the Fosi has speaker protection or not, but I wouldn't be surprised if they do. ASR reviewed them and probably mentions that.
