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?

@chungjh   are you sure the issue is with the amplifier and not with room and speakers?  
or possibly the preamp or preamp tubes?
have you tried different tubes for the sachs preamp?  
most 6SN7s can be overly smooth.  
just trying to help you avoid chasing the wrong dragon.  
Getting back to the original question about a highly resolving amplifier my current Pass Labs XA25 is very resolving and transparent, some say the most transparent and resolving they have ever heard. 
It is much more so than the Parasound a21+ it replaced but not a night and day difference.  
The ultimate transparency and resolution you hear is a function of every component in the chain, the amplifier being one part.
