Hello,
The Air Tight Retailer of New Caledonia lent me the ATM-2 for one month :
I used before mono amp class D GhentAudio.
The ATM-2 sounds very good, it's more smooth and have enough watt to drive my Cabasse Baltic
I will soon have the opportunity to have a test with the McIntosh MC275. Maybe it will be difficult to choose wich one is the best!
