This amp is the perfect match with my Synergy preamps. Having it rack mounted with midi capabilities for solo boost is just an added bonus. Highly recommended the company makes great products and they are reliable.
I've been playing for over 30 years. Mostly metal. Great power amp. It makes anything sound better. Fractal FM3 into the PA50 then the PA50 into my v30 cab. Done. Compact, simple, and sounds great. I really like the top, bottom and NFB controls. Top is like presence, bottom is like resonance, and NFB can tame or increase top-end sizzle. The hifi mode is interesting. I thought it was just a fancy way to distinguish between line level and instrument level. However, hifi seems to add more presence/feel - and helps put the signal more in your face. Hifi helps a modeler come to life and feel like a real amp. If I turn-on hifi, then I usually increase NFB to tame the high-end a bit.
Also, plugged the Ceres into the PA50. Helps the Ceres come to life even more. Great tight sound.
Solid state power amps just don't do the job. Tube power amps are better - and this one is great.
Awesome! I think I'll be selling my Mesa 2:90 power amp.
