If nothing else I can stare at my Garrard with Ortofon while I listen to my VPI with ET II.
If me Harry, I would first put your ET II on the Garrard using the quick install technique I described; then you can hear for yourself what the Garrard (the table itself) brings to the table. Apples to Apples.
Anyway, that is what I did with my Jean Nantais Lenco. It actually came with the Dynavector tonearm. Jean Nantais’ preferred tonearm. An impressive, freaky looking thing that Dyna tonearm. He was surprised when I sent him pics of the table with the ET 2.5 on it. hah hah
So my JN Lenco table is just sitting there, can be stared at as you say. It doesn’t bother me, not using it, because unlike digital DAC’s and CD players, it holds its value.....these days better than my oil stocks !
So I haven’t sold it off yet. Record players are so in vogue.
IMO - What you are doing Harry is a healthy audiophile exercise. I was happy enough with my at the time TNT TT, but My JN Lenco Idler table upped the game in a couple areas and forced me to make improvements to the modded TNT (adding thread), and also my SP10 DD setup (better isolation). So for a time the JN lenco, with the 2nd ETII on it, became a reference point for me. It’s been quite a number of years now . The JN table can be sent to him in Ottawa to have the latest updates made to it, but the delta that exists with the Verdier is just too large, for me, so I have not bothered doing it.
