Adding a tube amp is a good idea?

My only hesitation with tube amps are the heat and the the potential of endless tube rolling and life and cost of power tubes.  In addition, I would probably drive myself crazy trying to figure out when to replace the tubes.  My solution is my tube pre amp and solid state monoblock amps. 

I concur with goose and some others, that driving low impedance, power demanding speakers with a tub power amp, no mater how good they may sound,  can be a never ending and expensive battle of replacing blown tubes, fuses and resistors.

For a couple of years I drove my 87db. 4-ohm Maggies with a 100W tube amp with KT-120 tubes. The sound of the Maggies with the the tubes was incredible. But, even though I listened at low to moderate levels, two times I had tubes blow. Not only did I have to replace tubes, but also resistors and fuses, turning into an expense and headache.

From now on, I'll stick with a tube Pre. combined with a high current power amp, or a hybrid integrated amp, to drive my Maggies, as I have no intention of giving up the Maggies.

It appears that your speakers might be a little power demanding, so is something to consider.

Something else I might mention - even though the volume knob did not have to be cranked much (less than a quarter) to get plenty of volume for moderate listening, the demand was still there, taking its tole on the tubes.

I would keep what you have or consider an amp that is all Class A.  I've heard the JA Pulsar Graphenes with both Sugden and Pass class A amps and to my ears, that was a great pairing.
