Just did A-B comparison on fuses with digital and analogue. For vac 300.1a in rank order best sounding to less best:
1. Stock fuse (most ambience and roundess - front to back depth)
2. Hi-fi tuning left to right facing fuse holder (reduced some glare but flattenned front to back)
3. Hi-fi opposite direction (flattened and deadened sound)
In all other applications hi-fi wins (all other components incl speakers) but with vac amp i am not feeling the love.
