Exceeded: PSVANE Acme 805 and 300b tubes, NOS 6SN7 and 6SL7 tubes to replace OE tubes on Line Magnetic LM805ia. Night and day difference. Do it before any other upgrades. _____________
Exceeded: DIY rca interconnect project using Duelund 16ga non-shielded wire. These blow away my Cardas Golden Reference cables. Best part, Duelund project $70. ____________
Exceeded: Generic Cat5e to Supra Cat8 with Etherregen. Almost no noise and black background. Better bass response, wider and taller soundstage, improved depth and image coherence.
Not worth it: Lower than “Carbon” line in Audioquest cables. Start from “Coffee” and work your way up from there.
