RE: Burson V5i Opamp Upgrade Report Update

I substituted a Burson V5i opamp for, originally, a 741 opamp, but actually, I had already upgraded to an LME49860 which already was an improvement over the 741.

The Burson V5i seemed so much better, that I've listened to it only 4-5 times. It made me think of all the other parts of my system that I want to upgrade and got me depressed afterwards!

Anyway, most systems have soldered in ICs which, IMO, are NOT worth the bother to unsolder. Might as well sell and buy better equipment.

I replaced the output op amp in my phono amplifier board from Lehmann Audio, which is a German company. Their PCB tolerances are so tight, that they are almost impossible to unsolder. I told myself that if I have to rewire each connection individually, I will do so, and that's how I got through it. You put enough solder on, and it covers the gaps where you destroyed traces.

Overall, I didn't want to invest in another phono stage and I am sufficiently happy with it that I was willing to take the risk. I've now upgraded the output op-amp (difficult) and the power supply (easy) and did new casework (not so difficult).
