After 20+ years with Avanrgarde Duos I made th eswitch to Voxativ field coils. The Duos were and still are superb. The FC are slightly more cohesive and smoother and I might have just been itching to change. Could happily live with either
using a lot of Intact Audio iron, inter-stage transformers, output transformers, and power
supply chokes.
SP14 Tubes4hifi preamp heavily modified
LinLai 6SN7, oil/film caps for power supply, removed B+ regulator, Slagleformer on output for volume, etc.
Garrard 301
completely gone through and upgraded. Stainless steel platter and brass bearing from Peak Audio UK. Motor serviced with new bearings, and just about everything else that can be replaced/upgraded including a DIY plinth. Very happy. This is an end game turntable.
