excellent service and very fast shipping arrived well in advance also the power if the heatsinks are cooled with fans one for each heatsink or one large fan for both behaves well. However, the sound quality is poor, unacceptable at intermediate volumes. The output signal is pathetic, I don't understand the reason. While at low and very high volume it is okay. I will try to change the operational amplifiers in the hope of resolving otherwise it is to be thrown away.

ottimo servizio e spedizione rapidissima arrivata abbondantemente in anticipo anche la potenza se i dissipatori vengono raffreddati con ventole una per ogni dissipatore oppure una grande ventola per entrambi si comporta bene. però la qualità del suono e scadente, non accettabile a volumi intermedi. il segnale in uscita e penoso non capisco il motivo. mentre a basso e altissimo volume e ok. proverò a cambiare gli operazionali nella speranza di risolvere altrimenti e da buttare
