Doh! Modding vs. Selling

I have been modding equipment for many years and don't worry about resale as I rarely sell, in fact I usually purchase used so the previous owner has already taken the depreciation 'hit'.

In most cases I do the mods in steps rather than all at once, this way I can understand what each does.  It also keeps me from flipping equipment as with most mods you get a new and generally better sound.  Of course there are risks if your mod isn't implemented correctly and you then have repairs to do, but that is part of the 'fun'.

I love the smell of solder in the morning...

Hifiman5 - yes I do my own mods.  Although I have an electronics background my first significant learnings came in the late 80s from Audio Amateur.  The learning process never ends and there are plenty of enthusiasts at diyaudio.com or audioasylum.com
