Because my answer might depend on that, esp. if they are three ways.

assuming that like most tube amps you have some headroom.
Let's rate the Citation II at 18dbw (64 watts) to add to the 101db. That's adding just 4 watts which is reasonable, given that the McShane PSU upgrades have been done as well as the audio ones.And, with two speakers you get an extra 3db.
So you can get 122db un-clipped at 1 metre, possibly as much as 125db.
Which is almost? enough even for Mahler or Wagner at full bore.
So, I really can't see how you need the extra loudness.
I have heard several strapped PP stereo valve amps and they weren't as nice or detailed as the originals.
If it were me I would be asking Jim if there are any niceness / nuance upgrades to the Cit.II.
OR spend the money elsewhere, on the room, or your inputs or pre-amp.

Tim you are right on all accounts, and this is just a project I was just thinking of, for something to do, My Cit II is beyond McShaned and I added some Samra hot rods to it:)
However, I did like the change in these speakers, which as you found have no cross over, it's just a wizzer cone with a hyper tweet, when I tried these with a 20 watt amp then switched to the 60 watt amp. I like how they stiffened up and the bass got tighter, I thought maybe more power would tighten them up more, which I like. I am not looking to drive music at ear splitting levels or cause an earthquake. I realize I have more power than the room can handle already. I listen to everything but mostly Jazz and Rock. Intention was to do more power to tighten the bass, but who knows it might not get any better than what it is.
I didn't like how it sounded on the one speaker when I put it in parallel, it sounded horrible.
Pretty much with the feedback though, this doesn't sound like a good idea and everyone seems to indicate there will be sound quality loss, so I just might put this to rest..
thanks for your input,

If I had the Zu Soul Superfly and two citation amps, I would look into a pair of Subwoofers driven by a Marchland tube electronic crossover. Alternatively, I would strap one amp and drive a Mono subwoofer. You will need to go big on the drive to be able to keep up with the "satellites". Having the same amp driving to subwoofer and the speakers, with the tube electronic crossover, would sound a lot more integrated that the usual sand amp sub.

Dave,
that's an interesting idea, I thought of that once, but you know it's really hard to find passive sub woofers at all, say anything of quality. It seems you'd be left with trying to build a pair which could be a complete shot in the dark on how they would sound..
I do agree with you that if you could have it run by the same core system, it would sound more integrated..
interesting idea..
