I thought you might like to know that you have provided to me a product that has changed, for the better, my listening experiences from this point forward.
I live in the U.S. and own a Quad QC-24 pre-amp connected (all interconnects by Kimber) to a new Roksan Caspian power amplifier, powering Morel driven personally designed and built 17 liter sealed box speakers (speaker wires by PS audio) and filled out on the bottom by a Monitor Audio FB-110 powered sub-woofer. Front end is an elderly but still virile, Pioneer Elite PD-65
cd player. Numerous vibration damping, carpet fiber defying, interior room resonating cancelling, devices are in place as well.
When the Quad pre-amp was first hooked up, there was too much voltage between the Quad and the Roksan, and no way to attenuate. The sound was offending. I offered my problem to the "inmates" at the "Audio Asylum" forum and a gentleman from Yugoslavia, who also attempted to add a Quad QC-24 tube pre-amp to a solid state power amp, in this case a Quad unit, found great improvement placing your attenuators between the two components. To make a long, very interesting story a bit shorter, I found your web page, located your dealer in Vancouver, British Columbia, Canada, and 7 days later, wired up and ready to go, began rediscovering my entire music collection.
In any event, this is just a note to thank you for making this product and having it available on a world-wide basis.
