I’m honestly going to probably go krell or audio research if the place nearby will let me finance.

Let me chime in on the amp for the CS3.7. I will be getting mine on Saturday and will hook up a single Benchmark AHB2 ($3K) which has 194 watt at 4 Ohms. My room is small. I think the slightly warm top end of the CS3.7 will work well with the very neutral AHB2. If it does I will get a second ABB2 to run in mono since this stereo amp was designed to run even better in mono (or bridged). A long thread on A'gon about this topic.

If the AHB2 is not a good match with the CS3.7. The Luxman m900u and the CODA #8 for $6K or the CODA #12 are what I would consider next. These 3 amps are much more warmer than the AHB2. I don't think I will need to go this route but the CODA's and Luxman amp should be rather good with the CS3.7.

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.
