Dynavector XV1T MUCH higher coil impedence

Have owners of the XV1T noticed that this is Dynevector's first low-output cartridge to have a very high output impedance? This means that if it is loaded down to 30 to 100 ohms (the way all previous Dynavectors sounded best) the XV1T is going to be over-damped: i.e. rolled-off and lacking in dynamics.

So has anyone experimented with step-up transformers with the correct step-up ratios, like between 10:1 and 15:1? Or what about people that have variable loading. What kinds of loads sound best, not to bright but not too dampled?

Have not used a step up but this cartridge needs at least 300 ohms to show its' pedigree.

It will sound lifeless at 100 ohms.

IMO

But direct into 47000 ohms is not really appropriate either, IMO. With accurate audio equipment, direct-in will cause the cartridge to sound too etched, too bright, too forward, not enough warmth. Or at least not best for "its pedegree". Yes or no?

High impedence MCs (like the XV1T) sound best with low step-up ratios. 1:13, for example from a Denon AU-S1, provides 280 ohms, which is a high load compared to most. Low impedence MCs (like the XV1S) sound best with high step-up ratios. 1:30, a very common ratio, provides 52 ohms.

So I think it is interesting that Dyanavector's new version of this cartridge demands a totally different transformer, to be loaded properly. And I am sure Dynavector users do not realize this. They SHOULD NOT just use the same step-up as they had used before.

The Dynavector XV-1s had a 6 ohm coil impedence. The XV-1t has 24 ohms. That is a big difference requiring a totally different loading to sound best, 4 times higher.

If somebody liked a 50 to 100 ohm load on their XV-1s, they will want a 200 to 400 ohm load on their XV-1t.
