Powering Infinity Prelude MTS

Wanted some input on how you's with the MTS are powering them and which way you prefer.

Do you power them with just speaker outputs from your amp?
Do you power them with the output from your preamp and then your amp?
There may be some with other type systems... chime in.
Which do you prefer? Why?

Have been trying both ways and can't really tell much of a difference except for the bass.

Seems like I get a little more bottom end with direct from my amp.

Short info on my 2-channel system...

Speakers: Infinity Prelude MTS
Preamp: Krell Audio Video Standard
Amp: Krell KSA-250
Cables: Monster Sigma

The original spikes screw in. Sp the first owner must have glued after-market spikes on them. If you're handy, recommend you try to fix the volume knob yourself. Also, when you do the RABOS measurements, make sure the tiny pots are all in the fully clockwise position. I love these speakers with 300B SET amps.

Thanks, I will check the bases and see if I can source the screw on spikes. Speaking of SET amp friendly speakers, have you compared these by any chance to Avantgarde or similar horn speakers? Any thoughts?

I own Tannoy 215 DMT II speakers rated sensitivity 101dB. Dual concentric 15" drivers with compression horn tweeters, i.e., one of the greatest speaker designs ever made. I love both the Tannoy and the Prelude MTS, but they sound totally different.

Those Tannoys are studio monitors, correct? They look huge. I also own a pair of studio monitors, the PMC MB2s, and no home speaker I've owned matches their lack of compression and clarity. Unfortunately they require a good few hundred watts of clean power and a medium sized room to come alive, hence my foray into efficient speakers for a tube based second system.

Yes, the 215 DMT II is a huge professional studio monitor, a.k.a. the poor man's Westminster. They look ugly unless soffet-mounted, but sound wonderful. and express every nuance even at very low volume. The Art Audio Jota HC amps with 300BXLS tube drives them nicely.
