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

Chungjh: we have similar room and in my experience near field is the best option .if you wanna try mix tube pre in your system with Pass try Audio Research ref.

Dear @mijostyn  : With a removable headshell tonearm design you always can take away mass, AT/Denon have headshell as ligther as 4gr.-5gr. .

In the other side the 545 review that Soundlabs posted in its site came by Enjoying Music and guess what, the speakers were reviewed mated precisely to the Pass 350 !

@lewm  the issue on the coupled transformer is not rocket science but just common sense that for what you posted I can think is different from mine. That's all. Pun is not intented. Period with.

Dear @honeyooi and friends :  ""  in my experience near field is the best option. ""

Absolutely true and not only because is almost the only alternative chu has but because is the way we can really appreciate MUSIC as if we were seated in a live MUSIC event at nearfield.

IMHO, if we want to learn how good is our room/system we have to have a several first hand experiences through live MUSIC seated at nearfield and only if we have that experiences we can in true evaluate not only our system but any audio system listening to it at nearfield position. 

For many years now it's that what  I did and do in my system tests whole proccess.

No, normally I don't seat in my place at near field position because I have not a dedicated system room.  has my room/system differences seated at near field than into my normal position?  of course there are differences and my quest is to tweak my system trying that both positions be as nearest is possible, a real challenge.

How do you like the allnic preamp?  Have you considered changing the preamp for another one?
