recommendation for a high end analog system

You can get headshell spacers/weights on eBay.

Google "Pats Audio Turntable Headshell Weight - 3 grams" from Scottsdale Arizona.

Thanks gents for the info on the headshell weight. I talked to Triplanar and he told me that the TP tonearm on AG is actually MK3, not updated MK6. It is from 1997. Do you think it is worth it for about $3200? It can be upgraded to MK7 for $1600.

We use Ortofon Concorde style.  So easy to swap carts.  Unscrew tonearm bit, remove, lightly push on new headshells,...few slight adjustments to counterweight  and tracking force, and back in business. 
   I’m under tracking force weight as what’s in the specs for the cartridge.     When recording LPs’, usually add an extra 1/2 or 1 gram to record, depending on the sound. Will play some songs to hear, before I record. 

$3200!!! Seems very high to me, but maybe that proves I am a troglodyte.  Especially in light of the added $1600 cost to upgrade it further.  Mine is about that old. I was actually at Herb Papier's house having mine upgraded to Mk7, or whatever was the final version made by Herb, when Tri was visiting with Herb to learn how to manufacture the tonearm. (Herb was the designer and inventor of the tonearm, and he made the whole thing himself in his basement workshop in Wheaton, MD. By that time he was farming out the manufacture of some of the individual parts, but he alone did the quality control and assembly.)  Since taking over, Tri has made some nice further upgrades to the arm in terms of parts quality and function.  Maybe if you can be patient, a later version will show up on the market for similar cost.
