KT88 or EL34 based tube amp for Titus ES

I use an Audio Space AS-3i with EL34s to drive my Titus Es pair. You can also get a KT66 version.

Various tweaks can make this combo sound very nice indeed. NOS driver tubes, Herbie's tube dampers and Iso-cup footers, a premium AC cord, an isolation transformer. These all contributed to clarity and timbre right down into the bass, but the two factors that seem to have touched bass the most are the stands and the choice of speaker cable. I am using Audioquest Type 4 partly because it does bass.

So yes, you can squeeze more bass out of speakers with limited bass response. It's a question of optimizing setup and tweaking. Perhaps for that reason you might choose to go the KT88 route, but don't reject EL34s out of hand.

I wish I was more familar with your speakers, but I'm not. I am familar with these amps and I think the PL3/5 offers you the best chance for success. If for no other reason that you have a lot more flexibility in not only selecting the different types of power tubes but you can fine tune it by changing the small tubes and the rectifiers in the pre-amp and amp. I use the PL3/5 combo for the bulk of my listening and have ultimately chosen 6L6GC's in preference to the EL34's, 6550's, or KT88's I have on hand. I've had them now for over 3 years and have had zero problems.

Good luck.........

I would suggest the PL2.It eliminates an IC.The 88s are my preference and rolling the 12ax/au will bring its' performance to another level.
I am not as enamored of the 3/ pre.Those who have had both (friends),have kept the PL2.
I have owned the PL2 for many years.Many who have heard it,thought it was a unit that sold for $3K or up.With 90db+ speakers and a tube friendly impedance,you won't ever look back (nor sideways).

I use the Triangle Cometes with my PL2 w/ EL34's. Great sounding unit decent at low volume, room is 12 x 20 open walls. More than enough power and with the PL2 you can try the KT88 or the EL34 as well as some other power tubes.
