Pass XA 200.5 versus X-600 for MBL 101D

The Pass 350.8 wonderful amp plenty of power.

Thank you for the responses so far, they are very helpful in knowing I will not need a mega watt output amp(s) for my speakers. With no dealers within hundreds miles of my home, the knowledge gained here is much appreciated.

What is lacking with your current system?

Your amplifiers are the last item that I'd consider changing if it were my system, however if you are determined to go Pass - I'd choose the XA without hesitation.

I don't think the 200.5s will work at all.

There is a reason MBL's own amps are Class A/B and extremely high power.

1985tqc hi, I would stay with the Parasound JC1's as being bi-polar output they can give more current than the Pass mosfets can. This is why MBL also use Bi-polar in both their big amps used to drive their top speakers.

As the MBL's are 81db and have 3.8ohm load in the mid bass and an evil -51 degree phase angle, which could bring that impedance down to 2ohms, and this is where bi-polar output amp shine for current delivery for you to get the best possible bass performance.
