Has anyone compared Rogue RP-7 to Cary SLP05 and / or Audio Research Ref 5se?

As I recall Garrett had purchased a pre-owned Airtight ATM-2 amp.  He decided to use a pair of Tung Sol 6550’s in place of the Russian KT 88 pair the seller had included.  The 6550’s died on the first power up.  Apparently the problem was that the tubes couldn’t handle the start up voltage of that amp.  Replacing a fried resistor and the tubes solved the issue.

Someone had a question about 05 vs 5se, DM me

One of the least discussed underrated preamp is Wavac PR-Z2.

I am yet to hear a preamp as musically true and balanced as this. It has the tube greatness but with pristine clarity, accurate tones and almost perfect staging.

Thanks @garyalex  and @ghdprentice  . That does sound like an interesting read and that's also interesting about the KT88/6550 swap.  A while back ago I retubed my v12 via Jim McShane.  He steered me away from KT77s. 

@testrun I’m considering the Cary SLP 05, moving from an RP-7 like you, and also into a GaN based amp (LSA Voyager 350). So I am very interested in how it is working out for you? And did you get the Ultimate Upgrade?

We have similar systems. I too have the Bricasti M3, and I was going to buy a pair of Joseph Pulsars, but bought Fyne F1-8 instead.

I also had a pair of Audions for a short while but returned them. I am surprised they have enough grunt to power the Perspectives.
