Preamp upgrade or new preamp?
Using a Cary SLP-05 driving PassLabs XA-60s into Goldenear Triton One loudspeakers. I was considering the Cary Ultimate Upgrade ($1600) which supposedly boosts the preamp above the $10k class. Could I achieve better sound by selling preamp (approx 4.5k) and buying a used tube preamp for about $6k? I like the Cary cinema bypass mode and balanced inputs & outputs.
