I haven’t been able to hear this amp properly but it arrived a little slower than expected even with the freight bump up. I think it’s super clean though I wasn’t prepared for the live heat sink tho and still don’t know whether I blew it up. Stand alone 2 of them should be a clean sound and on par with the original. Tho the pre amp is the key. A circuit as my technician says would be a great addition
well packed excellent amplifier did some small modifications, it sounds very good! I'm happy with it, recommended seller!
