High Fidelity Cables MC-0.5 Effect

So many positive experiences, I'd like to give the 0.5's another try. My amp was having problems at the time; hum and power tubes red plated. Maybe this affected the overall performance. Amp is in the shop now, bad resistors found  with low voltage from transformer.

Anybody know if noise from the amp (hum and buzzing)  would affect the performance of the 0.5's while playing music? The highs were not smooth with the modules installed and presented overall harshness, even though there were benefits to imaging.
   I purchased the amp (used)  about the same time as the modules.

When I returned the modules to the dealer, he was very surprised they didn't improve the sound of my system.

Just bought an MC-0.5 B stock at 40% discount, reposted ad.

@jerrybj,
Just listened for about 4 hours with the MC-0.5 in place and it’s staying there. I just might get another. No more need for the Blue Circle Thingee anymore. Loving the results would be an understatement. Sliced bread is now relegated to 2nd place. 👍

Also, thanks @lowrider57 for your perspective and impressions as it got me interested enough to buy one. It’s everything you mentioned, and more, without one bit of negative to relate.

It’s the most realistic presentation I’ve heard in my room. 

All the best,
Nonoise

I also bought a discounted 0.5 from Audiogon. I think the buzzing from my amp caused the harshness in my system on my earlier audition. So amp is in the shop.

Good on ya, @nonoise .
