What are the best tube amps for Klipschorns?


I hav a pair of Klipschorns and a pair of LaScalas used together. With sensitivity of 104dB each, these don't need much power. I have a 125wpc Mark Levinson 334 ss amp now that has to be attenuated 20dB before it reaches the preamp. I'm after the bass punch and extreme detail of the ML, but in a lower powered, lower weight tube amp.

Boa2, I've been told that tubes provide smoothness and warmth that can't be found in ss amps. On the other hand, I don't want to give up the punch and detail found in the Mark Levinson ss amp. I was hoping that I could have my cake and eat it too. If no such animal exists, perhaps I could power the Khorns with the ML amp for punch and detail and get a smooth sounding tube amp for the LaScalas in the center. The problem is would the different sound of the two amps fight each other?
Actually I have two Levinson 334 amps...one for each side. Perhaps I could sell one, and use that $3000 income for a tube amp. I could also kick in an extra couple grand if necessary.

I am using Placette straight line attenuaters instead of a preamp. The last thing these monsters need is additional buffering. The Placettes allow ALL of the detail through.
The salesman that provided me with the Khorns 30 years ago also introduced me to the Levinson amp. To me it's a winning combination. However, every other salesman I know, and every Goner say just the opposite...I need tubes to smooth out and soften the horns. Am I the only one in the world that's right, and everyone else wrong? Something smells fishy. I shared this dilemma with the same saleman. He said that he still recomends the Levinson, but would also recommend the Mac mc275 as a tube alternative. Jaybo provided the same idea. It seems like a solution is beginning to take shape. I'm going to borrow the store's mc275 and experiment with the Levinson and the Mac. Perhaps a combination of the two will work.

I have learned a lot today. Thanks for all of your help and suggestions.
Marco, wooden horns make this a whole new ball game. I'm going to check into this now.

I've thought about vertical biamping before. However, with all of the attenuators and interconnects required, this will probably turn into one expensive, counterproductive mess. I guess you know what the K.I.S.S. acronym means.

I got Al's ALK crossover for the Khorns which sounds better. I have never heard of the Crites crossover. Is that better than ALK?

I improved the bass of the Khorn in a different way. I built a false corner for each Khorn and turned the corners inward directly facing the sweetspot. This allowed me to move the Khorns in closer together to form an equalateral triangle with the sweetspot as all speakers should be. I don't know if silver wiring will make any difference in bass due to the large wavelength. However, thicker oxygen free copper wire should make an improvement.

The larger wooden horns would be no problem. All of my speaker enclosures are raw and behind a large screen made from high end speaker grill cloth.

Now it's time to check out the wooden horns.
