I had a Pathos Logos.An extremely competent amp with the right tubes(The stock Sovteks were awfull,Ei 6J8 and Siemens CCa were excellent,EH 6922 were good.)I was extremely happy with the Logos and was not really looking for an upgrade.Then the Gryphon appeared ,used,for $2300 ...I decided that it was too much of a bargain not to try.Turned out to be a very good decission.
Before the Pathos I had a Proceed PRE and HPA2,Valve Audio Predator,various Rotel int and pre/powers.
Gryhon house sound ? Neutral,detailed.PRAT excellent.It does everything extremely well.A complete sounding amp.Very difficult to fault.
Analytical ..? Yes
Dark sounding..? No,not in my system.I suppose, can be, depending on the rest of the system it is applied in.Its not a warm sounding amp.
Organic ..? Difficult to say...yes,but the Pathos were more organic sounding.Obviously tube amps will be more organic.I have tubes on the output stage of the cd player...has to be a tube somewhere in the system :-)
Gryphons build quality is excellent.
I cannot comment on the Plinius.How the Gryphon will match the Gallo's,also, no idea.
In my opinion,a used Callisto 2200 would be an excellent buy .Do you think you need a 2200 or will a 2100 do for the Gallo speakers ?
