Hello to all of you!
My first post is to ask help a newbie like me do the hardware mods to upgrade the SPL Volume 2 balanced preamp.
The inside pic is from 6moons review here http://www.6moons.com/audioreviews/spl/open_big.jpg .
The only thing that I can do now is to swap TL071CP input JFET op-amps in DIP8 connector, but even here I'm uncertain which upgraded type will work.
I've already contacted SPL and they confirm me the OPA134 will work but they like the sound of the stock TL071 better, they tell me the OPA627 isn't compatible.
I really don't understand why or which are the real alternatives or specs to look at for upgrading.
I'm also ready to change capacitors and anything is considered an upgrade.
Any suggestion and step by step guide will be greately appreciated.
Thanks
