Cheap tweaks...What would YOU reccomend?

Clean all of the RCA connections. There are several commercial products for this, I like alcohol (grain) and Q-tips. (disclaimer: I own no interest in Johnson & Johnson)

Anyone have feedback on Rightway Audio Top Hats (tube dampers)?

Hi. Yoby. I bought tophats and tried them on the tube on my SLF-1. As this model is a hybrid with 1 tube I can't tell you how a full tube amp or preamp might react but on this pre it increased the depth persception and seemed to snap or lock in the images. Now this is from memory as both pre and top hats are living at a friends place. They are quite heavy for the size of them....but, yes, they do work. Let's see what others have found with them...good listening

Definitely a dedicated circuit, and separate the amplifier outlet from the pre-amp/cd player one.........talk about an upgrade for free, I just regret not doing it sooner. Tons of base, sharper, smoother highs.......WOW

If you have allergies or some other condition that causes excessive ear wax, an over the counter solution of carbamide peroxide will help clean the wax out. You'll be surprised at what you couldn't hear before. Buy a kit to get the soft rubber bulb syringe first for flushing the ear with water after the drops have done their work. (Bausch & Lomb made the best bulb syringe, but they may no longer be available). After that buy the Debrox brand which IMO are the best drops.
