AGD Duet Monoblocks

I have the same Linn Selekt( with organic and utopic ps).

i use Burson Audio Timekeeper GT4 Monoblocks. They work for me with my Totem Tribe Towers, which i will upgrade to the Totem Tribe Thunderbirds.

You might consider either of the Burson Audio Timekeeper Voyager Monoblocks or the LAiV Harmony GaNM Monoblocks.

Here is a review you may be interested in.

Cheers and good luck

Yes great explanation  from agd.i wish more manufactures would comment on thier development.  As a surgeon i had to have the same policy as i don't know what the other doctor did i was not there but this is how I was trained to do  it and would explain the procedure. More than one way to do things .thanks

I have the Fosi monos with the Upgrade OP-amps, tuned to my liking. I would say that they sound very good. if I did not have my Pass or My Benchmark AHB2, I would settle with this Fosi. it drives my B&W 707 beautifully. no doubt about it. however, for the sake of discussion, it cannot come close to my primary amps. I guess speaker synergy is what's needed for this to sing and some of the posters above got it. I tried it all my speakers (Falcon Gold badge, ATC SCM, Klipsch, and Maggie's) the Fosi drove them well BUT cannot bring to you the realism of what the Pass or the Benchmarks can do. This I experienced it myself. So, if the Fosi sound great on your speakers, well that is all you'll ever need. 

I heard the AGD mono's at a show and loved them. 

I bought the Fosi amps and couldn't figure out why others would  listen to them. They sounded powerful, but had a flat 2d Soundstage. Just like most things, I guess it's up to the system they are in and what the listener is going for.

I have also heard the AGD amps several times and I think they pass all the tests. Take a look at the reviews on Enjoy The Music. I think they are right on. I have owned a GanFET amp for several years now so I have some experience with what I think can make them even better. The preamp you use can make a big difference in sound quality. I had used an excellent solid state pre but there seemed to be a bit of graininess. I was able to fix that by switching to a BHK pre the has a tube front end. Didn't change the sound much but smoothed things out was a good addition. The other thing I  did was to upgrade to silver speaker cables. It increased the imaging a great deal but I don't think it works with speakers that may be a bit harsh. If you get a chance to listen to the Orchard Audio Starkrimson Ultras you might be surprised. Don't let the price fool you they are very serious amps. Good luck and have fun.
