Good to hear about other combinations of New production tubes. Some of the traits that have been described regarding the treasures are pretty darn accurate.
OTH, Break In, Break In, Break In. It is so important with the Treasures as the Manufacture recommends. I listened to mine intially after I purchased them preowned and thought that they were nice but nice nothing too special. I believe they had around 100 hours on them.
I let them burn in through the radio and burn in discs to 400 hours. Never listened in between in my modded Jolia 302b. Put it back in the bedroom system and I think "Marvin Gaye" and had some great bedroom Mojo to set the mood

Never looked back.
I bought another set and tried them in my new to me acquired Dodd 120's and compared them to the Gold Lion KT77 Reissues. Both are good but the Treasures simply have that well rounded sweet midrange with nice clean non fatique high's. They are pricey. so much that I'm looking at the JJ's for the bedroom since the Winged C's are in there and I'm kind of bored with their sound. Tube goodness might be a nice trick as I can't find anymore deals on the Treasure's.
