This is an OUTSTANDING class a/b power amp, which is diffrent from a great amp at the price point, From a Staunch el34 tube guy of 30 years I'm happy to report that I'm now using SS, If you don't have super hard to drive speakers buy this thing and get off the merry go round of this hobby, to these ears this amp does things I've truly not heard from any SS amp I've audtioned in the last twenty years, most of the ones I audtioned sounded to me like they were "shouting" at me they weren't fully fleshed out, highs were great and bass was thumping but the stitching that held the music together took a backseat to some degree, some were better than others but for the most part they all had that in common, This thing is a different beast altogether, everything is fleshed out, energized if you will, The first track on Buddy Guys "Sweet Tea"lp sounded so good I couldn't stop laughing as in one of those WTF moments, Buddys voice has aged but he still can produce power and man oh man it was down right spooky, u could FEEL him picking that guitar, Next up, Reggae Sounds by Linton Kwesi Johnson, and wow no kidding about the BASS response, the coasters were shaking, my Zu dw6 speakers with the 10inch woofer were smiling, but the bass wasn't overloaded or flabby in any way, zero bass overhang! Two days later after being out of town, I was pumped to get home and spin some records, I was starting to wonder if I maybe overhyped my first listening session and tried to approach this session a bit more practical try to dissect this things character and I failed at that completely, first record played was the Plimsouls "Everywhere at Once" and all that practical jive went out the window, I just started to boogie, this thing has tone for days, I couldn't sit still, That was a late night, and looking at the records I played I was allover the place, just to name a few Circle Jerks, Miles Davis,Diamanda Galas, Peter Tosh, Sun City Girls, Slayer, Sinatra..I was listening to music not records to test a certain frequency, In my opnion many companies similar to Galion are taking the industry by storm, brands like schitt, and Zu come to mind, 20 years ago this kind of performance wasn't avaliable at anywhere near affordable price, I'm happy to say that my current system is pretty much bought direct (Zu,Schitt) but this thing is the crown jewel..the fact that this thing is so affordable is a cause to cheer, If making a connection to your mudic collection is a priority look no further...like I said it's a no brainer!...If I had any quibbles it's the color ( sooo tired of black and silver )and this of course is not Galions fault more of a industry gripe, however it is built like a tank and the finish is very well done, the looks are purposeful and just kinda blends, but when you fire this thing up you'll look twice...If you can live with 75 watts and these are a POWERFUL 75 watts then you have found your amp...I did
