Thoughts on SS bass. Tube mid and high tube pre

Based on what Dover suggests, if you were to bi-amp, why not run a separate amplifier to the Heil tweeter? While that would do nothing for power demands in the bass, it would at least reduce the effect on impedance of running the supertweeter in parallel with the Tannoy. (The two speakers in parallel reduce the net impedance seen by the amp, as I am sure you know.) The resulting increase in the impedance seen by the tube amplifier can only help it to cope with power demands. (Tubes do better as regards both power output and distortion when interfaced with higher impedance speakers as compared to the net of 4 ohms you may be dealing with now.) Also, or as an alternative, add a subwoofer with its own amplification.

I would think very carefully before doing this. Your speakers are the limiting factor here. I would go with Tekton. They have more drivers. The Tekton Moab for example has 17 drivers. So you could have 17 amps. If that's not enough the Ulfberht has 21. If you were to go monoblock that would be 42 amps. The only problem I can think of, bi is 2, tri is 3, octo is 8, but I don't know the word for 21.

The Bryston is a pro model so it has a gain control. I use the Heils because I like what they add. It maybe a slight hearing loss thing for me. I am not unhappy with what I have just thought I would experiment a little that’s all. I didn’t mention that I do use a small but quality sub that fills out the bottom end nicely.

What prompted the thread was the additional bass I get when I switch in a SS receiver that I have without the sub. Marantz pm6 120 watt per side.
So..... The sweetness of my P4 tubes combined with some SS bass could be a great combo.

The Latin prefix for 21 is

If you’re running a sub you likely already have SS bass. Try without the Heil. I bet the overall bass improves because you’re doing your main amplifier a big favor by increasing the impedance it has to drive. Just try it.
