Andy Kim - Needle Clinic


I wanted to put this post out there about Andy Kim of Needle Clinic, located in Bellevue, Washington. As many may know, Andy is a cartridge re-tipper. I tried to find some older posts to add my comments but couldn't find them. So I'll start another OP. I just got my Lyra Kleos back from Andy today. Here's my comments.

My Kleos sounded a little off lately, so I thought it should be checked out. I sent it to Andy Kim. It turns out all that was needed was the stylus required a cleaning and polishing. Andy reported back that the stylus only has about 10 percent wear; IOW plenty of life left.

So I remounted the Kleos today and have been playing all types of music: rock and roll, classical, and so forth. The Kleos sounds wonderful; just great. Kudos to Andy Kim.

Fyi -- some may ask why I didn't send it to Peter Ledermann at Sound-Smith. I seem to recall reading somewhere that he's been unusually busy lately -- and with good reason -- and turn around might be a bit delayed. Also, I'm not sure Peter uses replacement cantilever/stylus assemblies that match (or at least come close to) the original. Andy does.
Anyway, that is a bridge I don't have to cross today.

Bottom line: Andy turned my cartridge within a week of receipt and I am pleased.

Bif...glad to hear you had a positive experience. I'm going to be sending him my Delos for repair.

Really helps to read good things about a company. Peter, (SoundSmith) has done 6-8 cartridges for me over the years and all have been excellent, but I agree that he seems really busy these days, that why I thought I'd try someone else.
Give it a whirl and let us know how you make out. Is your Delos broken? Retip/exchanges with Lyra are just too da*n expensive. If Andy can repair the Delos to perform at or near original spec for a fair price, that's a win-win.
When a Lyra cartridge that doesn't play or sound right is returned to us, and it can be brought back to appropriate performance levels without replacing components (other than the washi paper dust cover), we typically don't charge anything.

This includes suspension readjustments, trackabiity adjustments, low-rider adjustments, replacement of the washi paper, stylus / cantilever / magnet cleaning, etc.

Such work is a routine occurance, and I believe that this would have covered Bruce's Kleos, had he returned it to us.

OTOH, Lyra does not retip its phono cartridges - we only do rebuilds (and adjustments as mentioned in the first paragraph). If a Lyra cartridge is worn to an extensive degree and/or damaged, it will be fully rebuilt to the latest (most advanced) production specification for that particular model, or replaced with a brand-new cartridge.

Regarding Sound-Smith, the styli that they use are several times larger (heavier) than what Lyra uses, and Sound-Smith's preferred ruby/sapphire cantilevers also have nearly two times the mass of the boron that Lyra uses, also Sound-Smith uses a different, simpler bonding method to secure the stylus to the cantilever (that requires the cantilever to be prepared differently).

To provide some numbers that you can compare to, the Kleos uses a diamond stylus that measures 0.08w x 0.12l x 0.5h (mm), with the playing surface comprised of a minor radius of 3um and a major radius of 70um. The Delos stylus is smaller (shorter), but has similarly-dimensioned playing surfaces (2.5um x 75um).
