I've been happy with my system but the amp is dead. I'm running a PS Audio PerfectWave DAC with Bridge 2, Audio Research SP16 tube pre, and a Bryston 4BST into Aerial 10T mkii speakers. The Bryston failed recently, blowing 2 fuses in the right channel. It's 3 years out of the 20-year warranty. In my conversation with Bryston, they mentioned an option for trade-in credit toward the 4B3 or other product and I'm waiting for those details. My local dealer (Rochester NY) loaned me an Atoll IN100, which (in bypass mode) is underpowered relative to the speakers but which gives me a sense of the Atoll sound. He suggested the Atoll AM300 (https://www.atoll-electronique.com/en/products/power-amplifiers/am300/). The 4BST gave 400 watts per channel into these 4-ohm speakers. The Atoll offers 280 watts per channel into 4 ohms. I'm interested in power to resolve detail. Typical listening is chamber music, orchestral, piano, acoustic world music, and some electronic composers. The 4B3 offers 500 watts per 4-ohm channel. I'm waiting to hear from Bryston on the trade-in credit and lean that way because the 4BST was magnificent. Any thoughts on Atoll, on Rogue (also on offer from my local dealer), on the 4B3, or something else with the power to make these big speakers sing?
