The only tubes I’ve enjoyed bass from are KT88 and KT120. I owned and sold a Prima Luna integrated because of this lack. Oth the PassLabs XA25 had vice like grip on my PMC Twenty26 speakers at the time.
Primaluna EVO 400 Amps/Preamp lacking bass impact
We have Primaluna EVO 400 preamp with 2 EVO 400 amps running monoblock. Focal Kanta No3 speakers.
We were hoping for a bit more bass impact. rolling the tubes in both amps might be out of the range we would invest here.
Mostly music but sometimes used in HT setup with SVS SB-4000 sub. since the sub has full bass management we could add that leaving the Focal full range and setting the sub for 50hz/24db.
As long as it is okay to have both balanced and SE outputs from the preamp hooked up at the same time? always wondered about that.
