companies that modify equipment...opinions

Reminds me of the saying about 'fools rushing in.....'. I find it amusing to see folks who immediately have a unit mod'd when they haven't even heard it and how often mod'd stuff appears in a for sale ad just after a mod is performed. And, concurrently how seldom we ever see an professional, or even user, A/B analysis of the performance differences.

I agree with Ptmconsulting. Don't mod unless you KNOW what the result WILL BE, not just what some merchant tells you. And, FWIW I would never do a 'mystery' mod, or a mod which is not reversable unless I had actually heard and actual unit in my system in my room. Caveat emptor.

Upgrade Company gives money back gaurantees so you may want to add to your list.

Okay guys, and gals, who in our audio world is paying automobile mechanics to modify their cars? Seems the world is now being flooded with people who have chip replacement or 'mods', not to mention all the hardware upgrades that can be done. Some of these 'mods' can turn your car into a death trap. Lesson: for audio and automobiles, skip the mods and enjoy life.

I have had several friends who have had well known modders modify equipment, and they had to take it to a friend/electronics engineer to fix, and he said the work inside was worse than what he was doing in grade school. A 1500.00 mod, on a preamp added SS parts to a tube preamp???? And a tube preamp modded had paint sprayed inside,and the sound was now more like a transistor preamp. The tube magic was gone. There is a reason I don't buy modded gear, the quality is all over the board. Some mods work, but which ones????? The workmanship I have seen thus far is a disgrace.
I did have a friend with a Sony SCD1 modded, and his turned out good. Not all mods are bad.
Upgrading binding posts, caps, etc. is not a real mod IMHO. It is part swapping or upgrading, the circuit stays the same. It is circuit mods that bother me. jallen
