Stand alone tweeter?
I just got done evaluating 3 PS Audio Noise Harvesters in my system.  They are very good at smoothing HF in my system before I got an isolation transformer.  Now that I have an isolation transformer in my system, all my noise from my power is clea... 
Best Capacitors for Crossovers
Coils make a big difference in my limited experience. I added a pair of Fostex super tweeters to my system and was using Goertz Audio Foil Inductors (http://www.bridgeportmagnetics.com/contents/en-us/d68_Foil_Inductors.html) and my super tweeters ... 
power cords with active shielding
Guys, thank you for your feedback!@kijanki My power cords appear to be picking up cellular activity in the 700-900MHz range.  So you say twisting them will help reduce the cellular signal I seem to be picking up? 
Record and Stylus Inspection
@whart Very nice...I too have the ML2, they are very very special comrade. 👍🏻🤓 
Record and Stylus Inspection
very difficult to set up for a stable, focused imageYes, I agree. Here is what I use, it comes with decent base. Has manual focus too, so you can dial in your focal point (the stylus). I only use this to align my cartridge. It does not have enough... 
Power Conditioner Advice please...
I'm late to the discussion, but I want to share my experience with installing an isolation transformer into my system.  I have tube system consisting of class A mono blocks, phono preamp and line stage.  Together all components draw about 5 amps f...

@willemj Great link, lots of interesting articles there.  Thanks. 
high frequency intermittent noise
I’ve added a photo of my racks so you can see what I’ve done. Basically I’ve lined the racks with aluminum foil, then draped an aluminum foil tent over the power distribution center where all the power cords group together. Time will tell... 
Let's talk power cords
@willemj I know, but, when I used another power cord - a standard power cord, not a thick audiophile one - I was able to influence the noise by moving the cable, twisting the cable, and then I realized, it was acting like an antenna.  So I *think*... 
Let's talk power cords
@thirsty93 You will find a general question on these forums to be taken very seriously. And this discussion has been very good, showing you just how important a power cord is to a system.My power cords (Harmonix Studiomaster) are now picking up ce... 
high frequency intermittent noise
Using tin foil (thanks @jea48 ) I was able to reduce the level of the constant noise that was out of balance - the right channel was measuring at about 58-60db and the left channel was measuring at about 53-55db.  This was done using a Radio Shack... 
high frequency intermittent noise
@erik_squires No problem, I have 30 days to return the Furman.  But I think it's a keeper.  The issue presents itself with only the bare amps turned on.  I was using only 1 amp only for some testing.  Even the powered speakers have this issue.
