Surprised by Synergistic Red Fuse on Source for 99

Hello Hifial.

I confess I have changed fuses in my Metrum DAC, Lamm pre, and McIntosh amp and, like you, can barely hear differences. I can, but they are subtle. I tried HiFi Tunning fuses and now have SR Quantum fuses there...

But wanted to ask you about the fuse change you had done to your amps: did you replace the internal fuses as well as the "external" fuse (the one we can generally replace without opening the amp)? And what kind of amp do you have?

Mine is a McIntosh MC275, so tubes, and I only replaced the "external" fuse. So you have me wondering.
FWIW, I installed Bybee's Small Slipstream Purifiers (his cheapest) on the RCA inputs to my amp and they made a way more significant improvement than fuses - and they aren't exposed to blowing up, like fuses are :-)

Anyone else concur or having heard it found it otherwise?

Yes, I have similar results after replacing the HiFi-Tuning Supreme in my pre with Red Fuse. It's difficult to contemplate how a little fuse can alter the SQ by this magnitude.

Knghifi,
You findings are intriguing. I use the SR Quantum fuses successfully, these red versions could be even better.

Charles1dad,
For $90, you gotta give it a spin.

These are my favorite tweaks, inexpensive and excellent ROI. Another one is Cardas and AQ caps for all you unused RCA and XLR connectors. Cost me few hundred bucks to cover all the connectors.

You don't need to spend big $$ for a Tripoint Troy to get these improvements. LOL!!!

Hi Knghifi,
I hear you regarding the Red fuse and I'll get some soon. I must admit that the Tripoint Troy is not inexpensive even used. I'll also tell you that it's a brilliant addition to my system, I'm thrilled to own this superb product.
Charles,
