Wizards are great amps, no doubt. I would say to the OP may wanna just go with either Wizard or Naylor, but I like Naylor as a whole a bit more for my taste and Wizard is out of the OP's budget
I don't hear the Fryette as being more hi-fi than the Wizard, but rather just more modern and less organic. Amps like the Diezel's and whatnot are not at all hi-fi in my mind the way others describe, but rather just modern, compressed and synthetic sounding, which is often incorrectly used interchangeably with hi-fi. True hi-fi tone imo is the Schroeder and Alessandro amps I've got, but those amps are more suited for low to medium gain type stuff. Those amps have a level of clarity, detail and solidity to the notes that is actually what I feel hi-fi tone is. Those others amps aren't actually very good in regards to hearing lots of detail to the notes. The Schroeder is modern sounding, without being at all synthetic and the most open sounding amp I've heard. More than even my Hiwatt. A lot more actually
As for Splawn, many will disagree with me in regards to that, but I had once QR's from 2005, 2018, 2012, a Nitro, Mesa/Boogie Mark III, Germino and Helios all in the same room and it was clear as day to all of us there how much worse the Splawns sounded and felt in direct comparison. No way in hell was it a raw amp compared to those others, especially the mark iii, but I admit if only the Splawns were there I could have maybe liked them decently well, but they were just getting exposed and humiliated in that context. Hard to explain, but compared to the other amps the QR's were all sounding bright and brittle yet still in a way muffled at the same time, not dark though at all (except for the Nitro), hollow and just badly voiced mids, terrible feel. Going to the Mark III or Helios was like removing a blanket despite them not actually sounding brighter or less compressed and they just had an infinitely more detailed, rich tone over the Splawns as did of course the Germino. I've had many other experiences besides that with Splawn's and never liked them, unless they were the only amp I tried in the room and even then still never loved any. Something about the Splawn's voicing is just weird/off to me. Like even when I've AB'ed them with Friedman's, somehow going to the Friedman's also had this effect of removing the blanket from the speaker even though the Friedman's are clearly darker sounding amps. Not sure what it is. It's like they're filtering out some frequencies maybe. Not a good thing imo
