I wanted to share my latest amp project, the VTA M-65 mono blocks. I really like the sound of the ST-120, but I wanted to add a little twist of my own, so I decided to duplicate the ST-120 but in mono-block form. Luckily Roy has just introduced the MK 3 driver board which is identical to the ST-70-120 driver board but for mono amps, and about the same time a set of used M-125 chassis became available. So, I ordered the ST-120 transformers from Bob and got to work! The sound is the same as I love about the ST-120's, very open and transparent, and they are able to reproduce a 1KHz square wave perfectly, no tilt, ringing or overshoot, just like the ST-120. The power supplies are now of course hardly loaded, which can't hurt the sound either. They sound awesome in my home theater system!
