I am enjoying my analog system, but what can I do to improve?

 What I find is that small ensemble music, like jazz, sounds very good. Large orchestral music such as Carmina Burana doesn't sound very good, even though the sound stage seems ok. I seem to be losing clarity of the chorus vs a solo singer like Diana Krall. I guess it is the room size thing.

@chungjh  : To fine tunning a room/system and evaluate that room/system quality we need a very well know overall proccess where one of the main proccess characteristics is to listen always the same tracks ( maybe around 10-12 different kind of music tracks. ) and must be tracks that we already know as well as the fingers of our hands tracks that we know its sounds really good tracks that the quality of the sound is showed at the must " natural " and " neutral " way as if we were listen it in a live MUSIC event seated at near field position and if possible that even we already listened in other systems. We can't make any kind of system evaluation using recorded tracks just at random with tracks where we just do not know what to look for..So you need to define specific targets for your listen evaluations/tests.

Digital tracks could be the better way for evaluation purpose instead analog but I'm not saying not use analog you can do it too: a mix of digital/analog tracks.

Dear @lewm  : Before your last post the OP changed his preamp and bougth a new SS preamp.

Just to clarify, Allnic preamp did not sound bad, just different to Benchmark. It just didn't justify the big cost differential.

If you are happier with the Benchmark, so be it.  Good news, in fact.
