VAC PHI 200 upgrade

I used to have a pair of Phi 200s. really nice sounding amps. 

You can try the 200IQ, the 202iq, or try a Phi 300,1 or a 300iq, 

just a suggestion but you may want to look at your source and preamp first before replacing the amps. You will get more bang for your buck there. 

Following!  I also have Phi 200’s. Super stable and built like tanks. I’m using Shuguang WE KT88 plus output tubes, which I like better than the golden Lions (which are not bad themselves). I don’t expect to make a change, but I’m curious. I am also soon to receive a CODA 16 solid state amplifier. It will be interesting to make the comparison with my Avalon Eidelon diamonds. I am curious if anyone has directly compared the newer VAC KT-88 mono blocks with the Phi 200s. I know they offer more features, but is the sound quality significantly improved? I have read one professional review that says yes, but I’d like to hear what others have to say.  Kevin Hanes told me that two Phi 200s is better than one Phi 300

I guess I am also implying that your choice of tubes might have some effect on your sound quality and satisfaction

If I wanted to try a different high-powered tube amp, I would probably try an ARC. If I could get away with lower power, that would open up the possibilities.

Thank you all. Given my physical space, I cannot accommodate an amplifier footprint any larger that of the Phi 200. I have been hoping that someone would weigh in on the difference in SQ between the Phi 200 and the various IQ models higher up the chain.
