I've been running my S-1EX speakers with a Plinius SA100 Mk 3 , but decided it didn't quite have the grip on the bass I needed , so started a search for something more grunty.
I had couriers forming an orderly queue to drop Power amps off to try, quite a smorgesbord of different Solid State, Valve and Hybrids.
Eventually I settled on a Vitus RS 100.
Sounds great.
I then thought , lets try Bi amping, as my Pass Labs XP30 Pre lets me tweak the balance between the Master and Slave outputs , can dial the "slave" in an out, which for me if the HFs , so tried the Plinius on HF and Vitus on LFs.
I had the Plinius on the left of the system , on the floor, and the Vitus on the RHS on the floor.
It sounded good, but felt it was a tad muddled , and wasn't as fast or imaging as well as I'd hoped.
Then purely by chance, I moved the Vitus about 6 inches away from the gain stages on the pre, and wow , what a difference, it all began to get more focussed.
I've now got the both the Vitus and Plinius as far away from the pre as my cables will allow, and it has made a huge difference.
I'm guessing the transformers on the power amps were throwing some noise into the system?
Not noise like buzz or hum, but something that was interacting badly somehow.
Pass Labs did say that if possible , keep the control box away from the 2 gain stages .
Worth a try if you can do it.
