I think the OP said he didn't like the puma because it was too "clicky" or "clacky" or whatever. I've read through the TecAmp threads and don't remember that anyone has said that the puma amps are clicky, quite the opposite ("smooth", "warm" etc.)
All I'm saying is that I don't think the OP should listen to anything other than his own ears to know whether he likes an amp or not.
Nope. One of the signature tones of the Puma head is a very extended upper treble response, and a very present upper mid response. To some (either those who like a super warm old school tone, or especially to beginning players who have poor left and right hand control), this 'brightness and sparkle' up top can sound 'clicky and clacky', in that it uncovers ANY issue with technique).
Of course, this can easily be taken care of by a slight cut of the upper mid control, or a slight adjustment of the 'taste' overall tone filter, but again, that takes some skill in knowing what EQ does, and what frequencies impact those tonal areas.
The Puma heads are quite unforgiving, and very widely voiced with the EQ/filter set 'neutral' right out of the box.
The RH450/750 are COMPLETELY forgiving, given their very compressed voicing, polite top end, and a dip in the upper mids plus a pretty good dose of midrange distortion baked into those heads. I've often described those heads as voiced to emulate an entire vintage rig.... they make you feel like you are playing through a sealed, one-way multi 10 cab, regardless of the cab you are playing out of. Kind of cool, if that is your thing. Yes, based on player feedback (I was lucky enough to be a part of the player team that provided input to the RH750 spec), the RH750 allows you to over-ride the baked in lo pass filtering of the RH450 to allow for a bit more sparkle up top, but the inherent RH voicing is still pretty similar between both of these amps.
Again, the Puma versus RH750 represent two VERY different tonal spectrums/goals, and sound very, very different, and neither one can be EQ'd to sound like the other.
However, 'clicky/clacky' (assuming it is not purely a technique problem) can be pretty easily fixed on any amp, and the Puma upper mid control (centered in that 800hz to 2K 'clack area') and the 'taste' filter (which can roll off top end) can pretty much take care of any top end brightness/sizzle that a player might not dig.
To me, for those who want a bit of 'classic' tone (i.e., a tube emulation sort of vibe that includes a bit of roughness and 'pleasant distortion' in the midrange), the two 'best' options are the RH750 and the Aguilar TH500. The Aguilar is less compressed (i.e., much bigger and more open down low), but both have that sort of 'rock' voicing (for lack of a better term) that provides a lot of punch, a warm midrange, and a bit of roughness/warmth up top versus the more 'hi fi' (as that term is used on this site) voicing of the Puma heads (wide, clean, extended up top, crystal clear).
IMO and IME!
