I bought this amp used (small means forced) and frankly I have no regrets. Even today, as my group has more money, I do not intend to change it. I use it as the main amp, with speakers Wharfedale EVPX215, so at 4 ohms, and it gives all its power without flinching. Its strong point: it does absolutely no heat and is very quiet. The weak point is the connection, only planned for banana plugs. I solved the problem by installing a permanent system of jacks in his rack. Price / quality ratio and excellent course I recommend it if you find a used buy.
