Message: Steve: Yesterday, I installed the UltraSonic SS-7s to 'dampen' two CV4058 Mullard tubes in my C-J PV15. I honestly did not know what to expect, being inherently skeptical about 'tweaks' and the hype that precedes them. C-J had provided me with tube rings, silicone I believe, when I did their C1 upgrade to the PV15. I employed two of them per tube. But right from the initial note, I could hear change that was quite astonishing, and that on tubes near the end of their life. The improvements are in sound stage, detail, clarity and overall presence, most surprisingly to me was the bass deepened, like by a lot.

I use Ohm Walsh 3 speakers with their latest S3.300 drivers; what came our of them never sounded better. The music I heard sounded really life-like from a system that I have come to expect to sound life-like. Everything just became a bit more engaging and fun to listen to. Really, I can't believe I got all of that for less than $40!

So thank you, Steve. Now I need to dig around the rest of your product catalog.

Message: Hi Steve -

Is there a way to lightly clean the Way Excellent II mat? I noticed some stray dust and fibers had made their way onto the mat. So far, it doesn't seem to impact performance so I'm inclined to leave it alone unless there is a method that you recommend. Thanks.

Webmaster's reply: The easiest way is to just dab the mat gently with a wide piece of masking tape. Here's a copy/paste from the information sheet that came with the mat: "To clean the mat, just dab the surface gently from time to time with a piece of masking tape to pick up any lint or dust. The mat can also be wiped gently with a paper towel or cloth lightly moistened with water, denatured or isopropyl alcohol, anti-static spray, or window cleaner."

Message: Have a thorens 160TD and looking at your mats what do you recommend ? Also does this improve the sound even if you don't have a macking set up? ie top of the line needle and amp?? Cheers

Webmaster's reply: Hi, Robert. For Thorens TD 160, I recommend a full-size Way Excellent II-3mm Turntable Mat with 40mm center hole. If you never use the pop-up 45 adapter, a standard center hole works just as well (center hole option is chosen from the Shopping Cart drop-down menu). Upgrading a Thorens TD 160 to a Way Excellent II turntable mat is always a sonic improvement, bringing out more of the inherent potential of the turntable, regardless of your set-up, cartridge, needle, amp, or other system variables.

Message: Hi there,
We have an old Philips Stabilotone radio and record player 1950ish. I've tried to find an identical model, it looks like it might be a version of B8X72A. Looking for someone in Victoria BC Canada that might be interested in it. It worked fine when we stored it in our basement years ago..a little nervous turning it on now, in case it might do damage...I'm obviously not a radio buff. I have good photographs of the radio.

Message: Hi Steve,

My entire system is outfitted with Tenderfeet and Iso-Cups under all my components.

4 Brass Cone/Spike Decoupling Gliders arrived today and went under the rack, they're beautiful!

The sound is dead quiet and musically involving in all parameters.

Thanks so much for your time and great service.

Message: I am probably the most skeptical person on this, and possibly any other planet. However, my new EL84 power tube was getting beaten to death in my Epiphone Valve Junior, and the tube rattle was unacceptable. Not sure what else to do, I decided to take a chance on the Guitar Amp UltraSonic 9. What could I lose with the satisfaction guarantee? After a week of use, I am amazed thus far with the results. I no longer detect any tube rattle, and between the new JJ's power tube and the UltraSonic 9, the amp sounds much cleaner and more articulate. Very pleased.
Name: Adam Moon
Message: Tenderfeet are an amazing product. Instantly my soundstage cleared up and there was better definition in all aspects. What I thought was a quiet system setup got even quieter with the addition of FAT dots to the speakers. You gave me back the enjoyment of my records again!
Name: Walter O.
Message: Steve, thank you. I have a McIntosh MDA-1000 DAC and removed the original feet and put the "Big Tall Tenderfoot" (from a previous order) under it. The difference is quite remarkable and unmistakable. There is a clarity and detail in the system now that I hadn't imagined. So I'm very impressed.

Message: Hi Steve-

I have some Spectron Musician III Ref 2 amplifiers that weigh 50 lbs each. Right now, I am fighting some upper midrange/lower treble aggression and congestion, which leads to a mild-to-moderate harshness and sibilance in this range, depending on the recording.

I am looking for footers to replace the stock footers and was wondering what you would suggest to use to address the harshness/sibilance, or simply to avoid adding to that problem, while clearing up the sound and providing improved clarity, detail, musicality and three dimensionality?



Webmaster's reply: Four Extra-Firm Tenderfoot isolation feet under each monoblock will isolate the amps superbly, bringing out more of their true inherent potential. Tenderfoot isolation feet have potential to improve or remedy each of the problems you've been fighting with.

Your audio system and all sonic qualities are not controlled solely by the amplifier, but is the sum total of all its parts, the vibrational environment, acoustic factors, and source electricity working together in synchrony. Addressing the amplifiers alone may or may not remedy the problems you've mentioned. You might need to isolate/decouple the speakers, isolate source components and preamp. Perhaps a mis-matched cable or interconnect is a culprit. Start with four Tenderfoot isolation feet under each amp, adjust the positioning and orientation of the footers for optimal result, and go from there. Might just be all you need to achieve a satisfactory level of listening pleasure.

Message: I received my Super Black Hole CD Mat yesterday, and I approached the evaluation basically the same way I approached the evaluation of SS-9 12AX7 dampers - expecting an incremental but not overwhelming improvement. I was wrong AGAIN ! This little donut is magic.On my CAL Delta transport it works miracles. I wont go into detail, but there is a stunning "naturalness" that was not ther ebefore. Each instrument has a life of its own now and have that live, you are there immediacy and detail. Halfway through my first test CD, I just went into right brain mode and fell into the music. No need to ask myself if it was better or just different. My music is so much more tuneful, melodic, whatever you want to use to describe it. I have spent maybe $60 on these products and EASILY gotten hundreds wort h of improvememnt. It;'s like getting new components every time. Miracles do happen and they cost about $30 each !!
