TC Electronic RH750 ???!??

+1 Perfect head for that kind of vibe.
Per Tom B's comment, the GK MB500 does a good job of this also, depending on your definition of what a 'piano-like' tone is.
As a sort of oversimplification, the F500 gives you a Steinway type vibe... very warm and clear and organic, while the GK is more of a Yamaha type voicing... more goosed... deeper down low, more 'modern' up top, etc.... brighter and bigger, for better or worse.
I find the GK amps a bit too goosed both up top and down low, with a much too high level of upper midrange distortion (i.e., the GK grind) for my tastes, but they are 'transparent' in that they will reproduce the lowest to highest frequencies and overtones of the bass guitar. The F500 is, to my ear, a cleaner, smoother, more neutral voicing that adds much less of its own voicing to an instrument.
The TC RH heads would be among the last heads I would choose if I was going for a transparent, clean, piano type tone. They are voiced and designed to emulate the natural compression of a tube amp when pushed, and they do a great job of that. But, they are quite organic, warm, and a bit 'blurry' on purpose (i.e., the vintage rig emulation voicing).
For a big, super clean, articulate all tube tone, the Genz Streamliner is the voice of god. Not neutral like the F500, but super wide like the GK, without the midrange distortion and the upper end goosing of the voicing... IMO and IME.
Sorry if this has been covered already, but it seems that TC Electronic has updated the Active Power Management document on their site. For all of us RH750 who wondered if our amps shared the exact same power module as the RH450, it seems it does not after all.

Thanks for posting. An interesting read, and it does seem to capture what so many of us hear. I dig it.Sorry if this has been covered already, but it seems that TC Electronic has updated the Active Power Management document on their site.

You know what, that was a great read. So it seems the power module is, in their rating, just under 750 without APM, and 450 with APM.
It's a great amp, I understand why they stopped coming on here, and I'm glad they changed the manual/APM literature.

Its a step in the right direction give or take. It would be ideal for them to incorporate the information into the actual manuals which still cite the original 'erroneous' wattage numbers, even if they're still measuring in peak rather than RMS, and name checking the power unit inside vs. the actual output power of the amp, which is what the real measure is.

Cool. Uffe had in fact responded a little bit ago to Vic and I confirming the RMS peak output of the RH750, but he said that he was working on something else, and it looks like this is it.

I'm going to double check those numbers, but our measured impedance is just DC resistance. If you look at the impedance curve, that cab's going to present a load that's pretty typical of an 8-ohm cab to your amp.
I would think that using the FET preamp channel of the Genz Benz ShuttleMax 9.2 (or 12.0 or 6.0) could fit that tonal bill as well.
It looks like TC hasn't revised the Rh450 pages on their website yet but the Rh450 specs are included in the new "Active Power Management" PDF on the Manuals page for the RH750.
The table in Jazzdogs post #827 gives the important information. The bottom line is that the RH450 has a 450 watt power module before the APM so TC did not LIE in saying it was a450 watt amp and the RH450 is not just a 250 watt amp with compression and limiting as some have said.
