companies that modify equipment...opinions


hi everyone, im wondering if anyone has opinions on these companies that do mods. this question popped in my head as i have been reading up on modwright sony 5400s/oppos.

i also see that vse (vacuum state electronics in switzerland for example) also does mods on the sony 5400 etc. i also came across some other companies(forgot names) that heavily mod cd players in the united states.

im wondering if anyone knows or has heard and compared performance from the same piece (front ends in particular) but modded by different companies... for example modwright tube mods vs vacuum state electronics level 7 mod on a sony 5400 etc.
what are your preferences and thoughts.

thanks

No interest in Mods, will destroy the illusions to own an stock piece.
Certainly they will no find a leaving on my side.
No car mods either audio...
my 2 cents, i am glad to hear so many of you against it!
Great
And it's still an over the top statement, IMO.

Equipment at any price level might benefit from a circuit modification, but unless the equipment is defective or dangerous to operate no equipment needs a modification.
I agree totally with audioengr in that it CAN be a great way to go but you better do your homework. This is to say that you shouldn't run out and have a mod performed just because of what you read or heard from others. I also feel it necessary to HEAR prior to purchase. The 1st level mod, changing out caps, resistors etc. for different more expensive ones won't necessarily give you a better end result but it is relatively inexpensive and easier to change back. The one area where improvements can be vastly improved are in the power supply as he mentions but this is risky business, you better know who you are dealing with and not be guessing or hoping about the end result. If in doubt DON'T DO IT! Some of the biggest "bang for buck" improvements in an component can be realized through modifications but again, they aren't all created equally.

The real downside to modifications, as mentioned, is that you will most likely not capture your initial investment unless purchasing used and the modifications have been performed from a known and respected business, cavaet emptor!
" a simple tweak almost everyone can do is to replace the cheap cap in series with tweeter with a really high end ones. I replaced the mundorf silver/gold with teflon v-cap in my avantgarde omega duos. the difference is dramatic "

How would that affect the warranty, if applicable.

Most vendors would not want end users mucking with their gear and then requesting support under warranty I would think.
"I agree totally with audioengr in that it CAN be a great way to go but you better do your homework."

Amen to that!

TO do the homework, one best be sure they are qualified or able to do it correctly as well!

I have no doubt Audioengr is qualified and knows not only what to do to do it right but what to do if something should go wrong. After, all, I believe that is his job.
You better be willing to invest the time needed to accomplish all this properly.

How many of us not in the home audio design and engineering business, like myself, can say the same thing? Are we better qualified than the engineers at say Audio Research to make these decisions regarding their products and do it right?

If so, maybe a particular companies products aren't all that great to start with and another should be considered.

I might consider letting a third party do such modifications, if they are currently endorsed or supported by the original makers to the extent of making certain mods without invalidating the warranty policy. Otherwise, I feel I might be wading into waters too deep for me personally to assess properly, especially if things head south.
