Hi Srama. The two above postees are right on-- treat your room. I've been there and done that, and ASC tube traps are great. If you added a tube pre-amp you would only have a little smoother irritating brightness. I envy your 20 ft. ceilings-- as long as your room isn't square you have potential for great music quality.
Alleviate brightness by using tube pre?
I was wondering if a decent pre-amp (I was thinking Anthm Pre-2L) would alleviate brightness when hooked up to my Acurus A100. Currently using the Acurus RL-11 pre, with Cambridge Audio CD4SE and PSB Straus Bronze speakers. Really, my problem is an extremely bright room (hardwood floors, 20 foot ceilings etc.) - the same gear sounds wonderful to my ears in a smaller, carpeted room. So, would the pre-2l help combat what are essentially room anomalies? Thanks!
