KT 150 Amp Options

I'm thinking so Charles and I also agree with Weesbeedad that simpler is generally better. The V4s are amazing, if you need the power but they also put out considerable heat which living in Florida is always a consideration to me and quite frankly I can't see where I would ever own a speaker going forward that would require that type of power. In addition the 88's have a lower output impedance making them ideally suited for different speakers.

Ayon has some KT150-based amps.

I think the new Jolida KT150 based amps are the fancy new two piece mono amps. Ditto on the Jolida 502p...I went in casually with no regard for terrifying heater supply disasters with KT120s and they lasted almost 3 years under hard use, sounding great (rig dependent maybe...but friggin' great). The KT150s I replaced them with have been tootling (audio term...meaning "to tootle") along perfectly for nearly 4 months and sound fabulous...I bias 'em at 500 as that's easier, and I'm not smart enough to know why 700 is better...in any case, note that relative to what the competition charges for tube amps, you could buy two 502ps and run 'em in mono if you thought you needed more heat in your listening area...but note that the factory modded 502s remain a nearly unchallenged bargain as a quiet running powerhouse of glass based electron manipulation.

Tubegroover,
As you know, Rebbi reports fabulous results using the same speakers as you have. He uses an 8 watt SET, and enjoys all genre of music with this set up. It would seem that the silver 88 amplifier with 80 W of power would be more than sufficient for your needs.
Charles,

Well Charles I'm more than certain that 90 watts, the case with the Kt150 tube in the Silver 88, is going to be more than sufficient. I'm going to find out tomorrow how the QS and DeCapos pair up.
