Will upgrading my amp for el34s to kt90s help?


Hello all, I have a rogue audio atlas amp with el34s. I find that the bass comes up short in comparison to my solid state integrated amp (peachtree decco). On my current setup I use my peachtree decco (used only as a preamp & dac). The atlas magnum upgrade incorporates kt90 tubes as well as various upgrades to the power supply. Output is boosted to 90wpc, however will this help my lack of bass issue? Additionally the stereophile review on this amp holds true so far, it is very hard to hear everything going on in gorecki's 3rd Symphony.
Thanks

The Atlas in Magnum mode is far better than the stock model and for only $600 more the power supply is substantially bettered as well as resisters .the EH kt-90
tubes are excellent now the amp has balls and finesse .
I like the sound of this even better than the stereo90
which is $500 more, also the caps are Mundorfs which are excellent German caps and bypassed with a 1% tolerence caps and the transformers are of super high quality ,Please remember you have 8 and 4 ohm taps take off the cover and try this for impedance mismatches of speakers make a world of difference especially on a tube amp ,also with the Atlas each tube is individually biased
and it is a snap with the excellent meter in the middle
meaning if a tube goes you no longer have to buy a pair.
For $1800 The Rogue Atlas Magnum is far better built and sounding than any competition at this price and looks way retro cool doing it .There is no overseas amp that is built this well, looks this good with sound to match
at anywhere near this price ,The Magnum is the way to go !!
