I upgraded the coupling caps on my NOS ARC VS110 (I believe they were WonderCaps) with TRT DynamiCaps. It took a good 200, maybe 400 hours for the new caps to fully settle in but I am very happy with the improvement. Are the TRT's the best to be had-without a doubt not, but the prices of the best caps don't make sense when you're looking to upgrade a $2,500-$5,000 amp IMHO. I doubt most non-engineer audiophiles understand what coupling caps do in a tube-amp. Peter of Symposium once gave me a long detailed explanation. I will post it here later.
