Name: Erik L, Decatur, Georgia Review: The dampers have a dramatic effect on the Winged-C 6550's, far more detail and depth. Name: Frank Haro, Triefenstein, Germany Review: The Dampers fits very well on my old Tesla E88CC. With red silicone o-rings on my tubes I got a resonating feedback around 1kHz. With UltraSonics not! Name: Neil Blakeman, Aylesbury, U.K. Review: Many thanks for the tube dampers, these are being used on a pair of Papworth MC 100s, eight tesla e34l blue glass tubes in total for the H.F. side of things. Stunning attack and resolution. The tube dampers have totally eliminated a glare to high hats, cymbal crashes etc allowing the amps to do what they are fully capable of. Many thanks for a stunning product. Name: Michael Blackwell, Knoxville, Tennessee Review: I want to congratulate you on your outstanding products. I have been using the same tube electronics for years, always knowing I had not achieved the sonic quality that was possible. However, upon installing your Ultrasonic Instruments, my equipment has now far exceeded my expectations. There is now the smoothness, clarity, tightness of image, and naturalness that we are all looking for.
Further, you have established a customer service that is next to none. I appreciate the time you have taken to give real time feedback. From the time the orders were placed, to the time the products were shipped, I was always in the know about what was happening on your end. The products arrived at predictable times, without delay.
You will be hearing from me again, very soon, because my plan is to complete the installation of your products on ALL my tubes. Thanks for making my audio life a pleasure! Name: Paul Douma, Chicago, Illinois Review: I just received my Ultra Sonic Tube Dampers and their effect is nothing short of amazing. I'm using them on my tube preamp which was so wooly and unfocused that I would bypass it whenever possible. (Even with some hotshot NOS RCA tubes.) Now, each instrument has snapped into focus, the image has expanded, and the bass is just rock solid. These little wonders have got to be considered essential equipment for anyone running tube gear. Thanks for this amazing and affordable product, and also for your consistently excellent service. Name: Paul Pearah, San Jose, California Review: Yes, this is just the ticket. Piano comes to life a bit with more realistic dynamics. My system was already very good at microdynamics but now it's a touch more so. Name: Sigmund Finman, Pennsylvania Review: I recently swapped out the PTFE dampers I had been using which were a definite upgrade from the stock dampers that came with my cd player. The new ones are titanium and they're remarkably realistic and glare and grunge free. Even with cryovaced, antique Siemens CCa tubes, I'm hearing a big difference in detail and punch. Everything is clearer, transients are more defined, lows are fuller and more extended, music has more punch and is more visceral and lifelike. A real good deal for $34 which included shipping. Note: they needed an hour or so to break in. After that, just sweet music. Name: Paul Burke, San Angelo, Texas Review: These things are dynamite. Works real good on my EF86 tubes, plus they even look cool. Thanks for getting it to me fast as well. Name: Ralph Würthner, Apriori Audio, Germany Review: Your tube dampers arrived yesterday and after insalling them my ARC CD7 sounded as good as never before! Installation was easy and sound improvement was clearly audible. Better bass, darker background/more silence, more microdetail, slightly better pinpoint imaging! These are great products, I already use them in my other tube gear. Name: Alan Zoric, Belgium Review: You know i'm surprised at the clear difference of the new "ultra" thingies over the "old" model. it was clearly audible: more focus, clarity, tightness. Name: Gerry Maroulis, Spring Hill, Florida Review: Hi there, I installed the Ultrasonic Mini dampers today and unless I am hallucinating I hear things that make me wonder. The sound became more focused, more accurate, more musical. I wish I mastered a better vocabulary to express what I am hearing but the gadgets are a KEEPER. Name: Marc Andes, New York Review: The dampers work great on the 845s. I had a hum that I thought was a transformer hum, but it turned out to be the tubes. Totally cured by the dampers. Now I want them on everything.
