Try sampling some new DACs. Finding one that plays nice with the Meridian and other components is key. Perhaps just take the player to an authorized meridian technician for a check up and a fresh dab of lube on moving parts.
Sounds like your happy with the new amps. I do believe the PMCs are voiced with bryston amplifiers, unless that changed. One DAC to consider, well within budget http://bryston.com/products/digital_audio/BDA-3.html
Just because its a Bryston pairing doesnt mean you will be as happy with it, Im not suggesting that to be so. But its one to look at.
