On the other hand I have been using Rich at True Sound Works for my Apogee rebuilds for over 10 years. I had him do a complete rebuild of my stock Duetta Signatures first and found them to be truly fantastic. I had been listening to the stock Duetta Sigs for several years and thoroughly enjoyed them as I was fortunate to have a pair in very good condition [and] with no bass buzz.
After their rebuild they were nothing less than sensational. Call me crazy but I was later presented with an opportunity to try Diva Ultimates which, as impressive as their potential was, simply overwhelmed my moderately sized listening room (13’x17.5’x8.5’) as their incredibly powerful bass could not be tamed. Finally I came essentially full circle, returning to my [ room-size-appropriate] Duetta Signatures but this time as Duetta Ultimates which I highly, highly recommend. Everything you love about your Duetta is naturally enhanced with an effortlessness that is breathtaking. Over the years I have fed them both high powered tube monoblocs as well as high powered solid state amplification and these speakers just open up and let the best characteristics of each glow with their very best attributes. You can hear the tube amps embrace you like a graceful ballerina live on stage before you or the grip and speed of solid state amaze you with the precision and dynamics of an Olympic gymnast...
The speakers are stunning and I’m 100% convinced you would agree.
Good luck and happy Lissn’n!
