According to the dealer, it’s best to have a cartridge with a lower direct current resistance (DCR) than the SUT. The XV1s is 6 ohm and the T2 SUT is 15 ohm (the A23 T1 is 2 ohm). That being said, no harm in trying the T1. Thanks for the suggestion.
Sleight misunderstanding here - the 2 ohm refers to the target range of the internal resistance of the cartridge, which is not the load that the cartridge sees. The T1 was designed for the Ortofon SPU’s, which range from 2-7 ohms internal resistance. The T2 was designed for EMT ( 24 ohms internal resistance ) and Denon 103 ( 40 ohms internal resistance.). Your Dynavector is 6 ohms.
Unfortunately A23 does not publish specifications for their transformers so you cant really know for sure. Stereophile measured the T1 and estimates it has a turns ration of about 30 which means the cartridges see a load of around 52 ohms ( 47k divided by 30 squared ). T2 is unknown.
I checked the Dynavector transformer - SUP200 - this has 26db of gain, which is a turns ratio of around 20 - load presented to the cartridge assuming a 47k input word be around 118 ohms.
So you dealer may be right, in that the 52 ohms of the T1 is marginally low - but its not far off the minimum 60 ohms ( 10 x the 6 ohm internal resistance ).
My concern is that what does "voiced" mean.
This is the issue with SUT’s they can be very twitchy with cartridge matching.
If your dealer sold you the Dynavector - perhaps he could get hold of the Dynavector SUP200 to have a listen to as well as the T1. This should give you an opportunity to see what is going on.
With regard to the tracking weight in your OP the 2.6-2.8 grams tracking weight in the TAS review is bunkum. Stay with the manufacturers recommendations - Dynavector tests the cartridges individually and I have always found the recommended tracking force on the test sheet to be very close to ideal of not spot on.
I usually set the tracking weight at the upper end of the recommended range for run in, and then reset the tracking weight after run in ( usually a coupe of weeks ).
Same with VTA - always best to recheck after run in.
Remember when you change tracking weight, the VTA changes and needs to be rechecked.
Nontwithstanding that really the cartridge should be sounding good after a week in my view - yes it will open up more, but it should there 90% after a week of listening.
The XV1’s are fairly neutral - but I have heard them sound both lean and fullsome through the mids - it very much depends on tonearm and phono matching and set up.
