Modification Services Q&A

 

Why should I have my product modified/upgraded?

Response Audio Co. LLC was among the first company to start offering commercial upgrades to tube gear and has been offering upgrades and modifications to tube products and loudspeakers since 1996. 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 12+ year track record and consumer feedback has never been less than spectacular. Response Audio Co. LLC has several thousand modified products now in the consumer market with pieces rarely coming up on the used market.

Why? Most audio products no matter what their cost, are built to a price point to obtain the most profit. To do this, they must keep their cost to build the unit as low as possible. How do they do this? Simple. They compromise on the quality of parts used. Now you are probably thinking that if you purchase a $2000 tube preamp and then spent another $1000 or more for modifications you should be able to find a stock $3000 unit that would be better. You would be wrong. That $3000 preamp was built with the same profit driven attitude and still uses bottom of the barrel parts inside. There are very few manufacturers out there using premium parts to assemble their products. Who's to say a $20,000 component will absolutely sound better than a $5000 unit with well thought out and executed modifications performed to it and using premium components. You just saved yourself $15,000. Hhmmm............

What products or type of products do you modify?

We are not a digital modification company. Never have been, never will be so please don't ask us to look at your solid state DAC or CD player/ There are other companies out there that specialize in these products. What we specialize in is vacuum tube preamps and amplifiers. Over the years, we have been known for taking some of the better Chinese tube products and turning them into world class products that compete with counterparts costing several times more.

What is involved in your modifications.? Why don't you list it anymore?

We use to provide every last detail of the work performed in our modifications as well as the parts used.  Over the years we have had many fly by night companies pop up and call themselves a modification company. Upon further looking into, their upgrades/modifications were identical to our but using sub par components.   We have spent years developing many of our upgrades and our upgrades and parts used comprise unique intellectual property and are trade secret.

Secondly, no other high end modifier or upgrade company is confident enough in their work to offer you a 5 year parts and labor warranty.
Ask yourself: why is that?  Aren't they confident enough to stand behind their work for such a time period? Maybe they don't plan on being around that long.

Our modifications include but are not limited to new capacitors, new diodes, wiring, ground layout and new resistors. Many of the parts we use are exclusive to Response Audio / Bella Extreme. Our unique components and techniques provide much higher results then most any kitchen table DIY modifications. The average consumer is simply unable to perform upgrades to this level of expertise on their own without the years of experience and very advanced techniques used in both the selection and matching of parts and in "voicing" each model to the preference of the end user. 

Simply installing high dollar parts into a component does not mean it will sound better. We have spent years evaluating countless combinations to find what sounds right in any given product. Sometime the most unorthodox combinations yield the best results and we are not willing to give our years of experience away for free.

Years of customer testimonials confirm that we have done our research and are able to provide you with a product you can live with and enjoy for years to come. 

What type of warranty do you offer:

Five year parts and labor, fully transferable. No, that is not a misprint. Our track record for reliability has proven over the years to be better then the original manufacturer because the parts and solder we use are the very best available. Most products on the market today are built to a price point to allow for the most profit and/or volume moved. We do not build to a price point and therefore do not use the cheap parts to modify products that are used by the original manufacturer.

What is your turnaround time on modifications?

There is no simple answer to this question. Times depend on the complexity of the mod as well as our current work load.

Do any of your modifications alter any the original functionality or circuitry of the product?

Most of the time the answer is No. However we have come across some products that required a slight change in circuitry to sound their very best and/or operate at proper voltages. There are other times when a sub par remote control volume pot is removed and replaced with a much higher quality design. This is only a functionality change that results in better sonic performance.

Can you provide me with the parts needed and instructions on how to perform my own mods?

For reasons mentioned above, the answer is no. Another reason is for liability. We are also not a reseller of any of the parts we use.

I started to modify my product. Can you finish it?

We will no longer get involved in products where someone has already attempted to modify it as these are usually a can of worms. Nor will we modify a product that has already been done by another company.
