Systems comparison

I have two systems

Both have acoustat trans nova 200 amp

both have dynavector Ruby low output mc cartridge 

1st system has arc sp 6 preamp second system has acoustat tnp preamp

first system has thoren 165 turntable 

2nd system has sme 3 arm


question is what are weak point(s) of each system

2nd question is if acoustat preamp is weak point what used arc preamp would you recommend?

also add any suggestions


How would you compare both systems?  After all, you’re the one who can listen to them.  How do they compare? What are the rooms like? What would you like that you’re not hearing from your present systems?

Plus you need to measure each system to compare, see my virtual system for an example
