Recommendation for a highly resolving amp


I have Don Sachs 2 tube preamp driving Pass Labs X350.5 driving Sound Lab M545 ESL speakers. I like the sound very much, but when I went to hear my friend’s Spectral system (driving Quad2912 ESL) I realized my system can benefit from having a higher resolution amp. Spectral amps need all Spectral preamp/cabling, which would be quite expensive. What would you recommend?

Due to a renovation type project at my house, I had to opportunity to have my system setup at a friends house for a while.  The acoustics of our two rooms are very different and my system sounded very different at his house.

I don't understand how listening to two different systems in different rooms could be sufficient to determine which component in one of the systems needs to be upgraded for that system to sound more like the other.
