Response Audio Modification Services

Response Audio was among the first to start offering commercial upgrades to tube gear and has been offering upgrades and modifications to tube products and loudspeakers for over 12 years now. There are those out there that do not believe in the use of high quality components, such as premium capacitors, critical resistors and quality wire but our 10+ year track record and consumer feedback has never been less than spectacular. Response Audio has several hundred modified products now in the consumer market with pieces rarely coming up on the used market. If you want to get a small peek at what our customers have been saying over the years, just look at our Feedback Pages.

Yes, some of our upgrades are expensive such as those for the Antique Sound Lab Monsoon and Hurricane amplifiers but once you see the quality of the parts we use and the extensive work involved, you will understand why they cost what they do. Once you hear these pieces, there is no turning back. We have dozens of EXtreme Hurricane and Monsoon amplifiers producing beautiful music in consumers homes and to date, not a single case of buyer's remorse.

NOTE: Response Audio / Bella Extreme does not sell modification "kits" or any parts used in our modifications.
