Have to disagree Ozzy.
While it is true that the Rogue lacks the common tube amp sound of yesteryears (slow thick sound, rolled off highs, loose bass, etc.) it sounds nothing like the solid state amps I have owned (Bryston, Sim Audio, Quad 606).
My Rogue sounds like the tubes I put into it. If I load it with Mullard EL34s, Mullard 12ax7s and RCA grey glass 6sn7s I can make it sound like a very tubby tube amp. Even with fast linear tubes like KT66 it still sounds like a tube amp.
Different tube amps sound different, just like different solid state amps sound different. If you don't like the Rogue sound, hey its a free country! Buy a EL34 amp with tube rectification if you like that sound. No right or wrong in this hobby, if it sounds good to you enjoy!

Well, taste is very personal and individual thing . I just tried to refresh my hibernating state after some 8 years sleeping by waking up and collecting different amps from friends and friendly dealers with newer tube types to refresh my feeling if I'm still ok or missing something. Actually my point was to check on KT150 coz I really liked CAT monoblocks sound driving some Raidho stuff during recent opportunity. So I brought to my home old Mac 275 with 4 kt88, very old but still alive and kicking Musical reference 8x El34,Ayon Triton 8 KT150, even Cayin with kt 88 and Lyric with kt150 for curiosity sake, also new AR 75 and Rogue with kt120.put it against my old and unfancy Cary 120 8xkt88 svetlana and small sli-80 with original EH kt88.Speakers were Kef Blade2, Wilson Sophia3,Maggie 3.7 and 1.7 as well. Making long story short:old Dennis Hud's stuff blew all of them out completely and Rogue was worst IMHO
Hi Ozzy.
I am familiar with the Cary amps you mention particularly the sli-80 integrated, which is one of the "tubbiest" sounding modern amps around IMO. Agree that it is about as far from the Rogue "house" sound as you can get with another tube amp. If that is the sound you are looking for than no doubt that the Rogue won't be to your taste.
Also agree that the Rogue amps don't sound very good with Tung Sol KT120.
My Rogue has seen quite a bit of modification and this has definitely resulted in a better sounding amp.
The KT150 is supposed to be a great sounding tube, much better than the KT120, too bad the Rogue can't use it.
Cheers!
Hi Mendel,
Yes I agree with you that your mods should bring definite improvement to the sound, however what struck me is not the difference in tubey/lush sonic signature but difference in amount of details and 3d of soundstage between all those amps. Handling of midbass/bass was another issue. Chinese offerings(Cayin/Lyric) were most guilty of fake tubey sound with no resolution at all. Ayon despite offerring most potent combination of KT150x8 was most sterile sounding, while subduing bass notes -- it also shrinked the rest of the bandwith and soundstage proportionally .All amps/tubes combination however failed on tube/ bass handling ..playing overcooked recordings like Stockfish label Cris Jones/ Moonstruck or Sara.K/Water falls or even Mark Knopfler 2002/The ragpickers dream/track#4 A place were we used to live(torture for tube bass) resulted in pure distortion. Wilson Sophia could not be bi-amped but fortunately Kef Blade2 yes. So I tried to run some hypex and bryston amps for bass only duty… It was not bad at all.. I was not satisfied with the blend but think that more carefull implementation via active crossovers and Dsp could finally resolve the issue. I will return from vacation in a couple of weeks and will try that approach or via computer with 8 channels/XO/PQ or via. MiniDSp stuff.
Cheers!
