I want to ask folks here about replacement drivers for the CS3.7. 

I am wondering if I should buy 2 tweeter/midrange drivers and keep in storage for potential future need. I plan to keep this speaker of years. 

Does the replacement of the driver just require unscrewing, soldering, and screwing the driver back on? Does it require any audio calibration after replacement to get it to factory spec? I have asked this question to Coherent Source but have not heard back from them yet. I thought I would also ask here too.

@thoft, tubes don’t typically like being driven into low impedances. The afore mentioned Coda amps might work nicely. 

I meant to say the new CODA #16 that is supposed to be super quiet.

I agree Luxman M900u would be what i'd choose if i couldn't find a Gryphon to drive 3.7s.

Luxman m900u happens to be at the top of my list if any place will let me finance.
