Response Audio 
Bella EXtreme Customs

Please refresh this page as details change periodically and new items are added.

For those who want to become emotionally involved with their music.

Tired of having the same 'me-too' components as the audiophile next door? 
Introduction
 Response Audio, over the years, has become known for it's custom offerings based on buyouts of discontinued products or companies. We then take these products and either modify or redesign the circuit to bring out the utmost potential the product has to offer. As most audio enthusiast already know, many tube products are manufactured in China. Some of these products are designed to strict standards of US based companies. The problem is that many of these products are made to what is known in the industry as "price points". What does this mean to the consumer? It means that some areas of the design or internal components are compromised in quality. This is where Response Audio steps in.

Response Audio will buy out these products and perform extensive upgrades and/or modifications to them bringing out all the potential they have to offer and released as an exclusive Bella EXtreme Custom. We do not build these products to an affordable "price point" rather design them for those who want only the very best in any given design as well as one-of-a-kind item. The Bella EXtreme Custom products are not for those looking for the 'budget component' although many have considered our custom products to be much more affordable than other exotic name brands offering a similar level of sonic nirvana.

Don't forget, we also stand behind all of our custom products with a warranty and servicing right here in the USA!!

Bella EXtreme 60 mono bloc tube amplifiers 
60 watt push-pull 6C33
 Available December 2006

Response Audio just bought out the remaining inventory of the ASL KMP60 FOX 6C33 mono bloc amplifiers. These units sounded pretty good in their original form and I am going to be redesigning these to be released as limited (very limited) Bella EXtreme 60 Custom mono blocs.
 They will see the same attention to detail and workmanship as any of our custom Bella products. The only aspect I am undecided on at the moment is the cosmetics but I will figure this out in the end.
 Here we have custom built  mono bloc amplifiers based on the 6C33 output tube running in push-pull operation for a dynamic 60 watts per side. Cathode follower, triode output. Includes external bias adjustment and meter to allow for simple biasing. 

Key features: updated 11/10/06

  1. Reference Grade Teflon coupling capacitors (x4 pieces)
  2. Reference Grade Teflon innerstage coupling capacitors (x4 pieces)
  3. Modified power supply.
  4. High-grade Panasonic low ESR power supply filter capacitors.
  5. Bybee purifiers found in the B+ voltage
  6. Mills non-inductive grid stop resistors
  7. Mills non-inductive cathode resistors for input/signal tubes.
  8. Dale/Vishay resistors used throughout.
  9. "Ultra Fast - Soft Recovery" diodes in the power supply.
  10. VH-Audio Cryo-treated Pulsar internal wiring
  11. WBT speaker binding post
  12. Russian 6C33 output tubes
  13. Powder coat Sapphire Blue, British Racing Green or deep Red face plate and transformer cover
  14. MUCH MORE!!
