VAC Renaissance Pre-amp owners - Help

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.

Hi Podeschi, thanks for the info.

What Hi-fi fuse are you using and do you have some hours on them, I know that sounds funny but they do change sonically over time. I haven't figured out why but they just do.

What are the stock fuses in your 300.1, glass or ceramic

Hi, Dev. I have the Hi-Fi Supremes all the way around -- they have probably 100 hours on them. The 300.1a came with ceramic fuses while the power supply to the Renaissance Mk III preamp came with glass. I just took out the Hi-Fi Supreme from the preamp power supply. The stock fuse slightly lost some of the harmonic weight and richness and delicacy the Hi-Fi Supreme provided. So go figure -- works like a champ in preamp but not so much in 300.1a.

Podeschi, I flipped the Hi-Fi Supreme direction in my VAC Sig MKIIa and I think I prefer your direction now. :-):-) Sounds is not as open but image is tighter and better defined.

Glad to hear it, Knghifi. I think that is the consistent sonic difference when changing directions (not as open but tighter and better density)
