Use for 3 months, very pleased with this amp. His impeccable behind Audiophony EH 110. I use 4 ohms 450W RMS into 2 x 2 x avec2 VDSG15 HQ Power 300W RMS and a Behringer Sub B1800X PRO 800W RMS bi-amp behind a VPA2350mb bridged 500W RMS in Mono, it gives a max of all perfect quality with a great sound!

I do it again the same choice, we must say that I did a lot of tests before deciding what gear is left at a very good price / quality ratio for a connoisseur!
