They are pretty good amplifiers stock, but the upgraded circuit from Bob Cordell makes them fantastic.

So I would say my P7.2HD drivers are fully broken in at this point. I have not driven them to distortion or exceeded xmax, or anything reckless like that, but lets just say the moving parts are certainly compliant at this point.

They've really smoothed out. Bass through to lower midrange has fully developed now. Yet, that sparkling top end is still there. I am even more pleased with them now. There isn't really anything missing except for the obvious SPL limit, which I don't find limiting at all. During my testing I was seeing SPL peaks well into the mid-90dB and a couple up to 100dB (at the listening position) which is actually far louder than I listen 99% of the time.

10 out of 10.

cogitech,

What are you using to measure SPL?

Yeah I always wondered about that when you could buy them factory built? Were the kits that much cheaper?

It was cheaer to pay Chris to build them than getting factoy built ones. And he did a better job.

NAD 3020 or Advent 300 and Hafler DH200 were a common pairing.

A lifetime ago, that was. The DH200/220 was a much simpler build than the original preamp, but the DH500 was a beast

Hey von Ah, here's a tip you might find useful (although I am sure it may have occurred to you anyway).

Save the plastic protective covers that are shipped on the P7.2HD drivers and use them to cover the drivers when not in use.

The only real peeve I have about the microTowers in the "Castle" configuration is how much dust and grime the top drivers collect over time. I often thought about making grilles with acoustic fabric but never got around to it.

This is a pretty simple solution and has already proven itself. Also reduces risk of accidental damage due to pets, careless vacuuming practices, thrown objects, etc. etc. I cover all 4 drivers, because - why not?

I’d suggest using a router to create a small rebate / ditch in a square shape, set back from the edges and fashion a grill cloth to sit on top with the cloth fixed to a square frame that simply drops into the routed slot.
