Benchmark AHB2. If you want more power you can buy another down the line and strap them. I do not own this amp but I have had them in my system and I do use Benchmark’s ADC. Benchmark is a commercial electronics manufacturer and their pricing is less abusive than Pure Audio companies. So, you get much more for the money. Their stuff is beautifully made, 1st class and surprisingly small but don’t let that fool you. The AHB2 handled my speakers, full range ESLs without any difficulty. VERY quiet, neutral, dynamic little powerhouse. The only other amp I am familiar with of the same value is the Parasound JC-1 which is no longer available new. The little amp runs circles around amps weighing and costing a lot more.
Oh, and with the money you save you can get another sub😎
