Primaluna EVO 400 Amps/Preamp lacking bass impact

@stobbe in my room I ended up 36" from the wall.

I have PrimaLuna Mono’s mated to a Dennis Had Inspire preamplifier. I have tons of bass, even while driving Electrostatics. I have no idea why you don’t. My thinking is, the issue isn’t the Mono’s!

…lacking bass impact…

just to be clear, is the OP looking for more bass energy or a tighter bass definition?

I found the original EL34's in the HP Mono  Blocks I use were missing too much. I  am driving ATC SCM19s that have a flat impedance curve with very little damping problems. I skipped the lesser tubes when I decided to roll and went directly to KT150s. What a difference! They've been in there going on six years and still sound fine.

After I finally got the speakers positioned properly the bass is crisp and fully present. Full disclosure: I added two REL T/7i subs to pick up the very low end that the SCM-19s don't extend to.

Rock, Jazz, Big Band, Blues, Reggae, Zydeco, Female and Male Vocals are all tonally balanced. I've heard a lot of live music and this setup does an excellent reproduction. Plenty of bass.

all tube amplifiers will have a low damping factorel34s don't have the current delivery of a kt88 or 6550

adding a sub is not the answer a good sub adds pressure to the leading and trailing notes of the mains 

you have a few options tube roll or add a solid state amplifier

we are a focal dealer if that helps
