the t.amp TSA 4-300

bought it for home use on a diy 2 way speaker with active crossover (xilica xp-4080). i know i know, it's a overkill. but i wanted a 4 ch class h amp. this amp sounds awesome. very clear, almost no noise at all even though it is so powerful (with the volume knob at max i need to put my ear on the tweeter to here the hiss and even then it is super low, for a 550w amp this is impressive) only problem i had was as i opened the amp to replace the fans (they are audible in a room but since they can change their speed they very silent, but not enough for a room) 4 of the case screws was jammed and i ended up having to drill them out (i did used the correct screw driver) other than that can't fault this amp, and for the money it's a steal... update... i have changed the fan to Noctua fans but still, it was too noisy for a room. in the end i have flipped the fans so now they blow air in instead of sucking it out, i also removed the filters from the front and got fan grills with a filter for the fans. now i finally have silence
