Are they the 1st or 2nd generations D?
They 2nd has much better internal parts. Caps, filters, wiring etc. Not that the 1st gen is any slouch.
If money is a factor then I would suggest a used Pass Labs class A amp with as much watts as your budget permits.
Or check out the DIY Hypex Ncore NC400 amps.Very easy to assemble. For info Audio Circle and DIYAudio sites. You will not be sorry. If money permits get two pairs and bi-amp. WOW!
