Dynavector XV1s loading & phono


Hi.

For those of you that have owned the XV1s, just curious as to what phono stage you are using with yours (or have used) and what loading you are putting on it to make it sound great!

I have got a XV1s at the moment, but with the Cary PH301mkII tube phono stage, have never got it to sound great. I was using the XV1s on LP12/Valhalla/Ittok II/rignmat anniversary. The default loading for MC on the Cary is 680 ohms. I modified it to make it about 150 ohms which did make a substatial improvment, however, sound was still very dull, undynamic, muffled, very unexciting.

I have heard the TeKaitorua (next model down) on a Oracle/smeIv setup going thorough a very modest solidstage phono/integrated setup and that gave extraordinary results! Likewise with the Lyra Titan, used through a solid stage Lyra Connosieur phono stage was absolutely amazing. Some people have replaced their Titan's with the XV1s! I don't think I'm hearing anything close to what the XV1s is capable of at all.

I think it is something with my front end analogue setup as my CD playback sounds spectacular, WAY better than the XV1s/Cary combo in every way. Since I have blamed the Cary for the poor match with the XV1s, I have since replaced the unit with the Kondo M7 phono - but as this is just a standard phono stage, I have had to revert back to my very modest MM Linn K18II cartridge. The Linn/Kondo setup is better than the XV1s/Cary in every respect - probably equal to that of CD playback in my system. To use the XV1s with the M7, will require step up transformers.

Question is:
1) What sort of loading are you guys out there using with the XV1s and on what phono? Tube or solidstate?
2) Is my deck/arm/PS combo the main cause of the poor sound from the vinyl?
3) What stepup transformers would one recommmend to match with the M7 - there is obviously the Kondo SFz ... any other worthy contenders?

Thanks a lot for all you guys help.

Regards

Doug Deacon has provided excellent advice on setting antiskating. If the advice still seems a bit daunting because of the subjective aspect of determining the result of changes, I have a bit more "objective" way of setting antiskating.

If you can find a test record with a monophonic test track of musical instruments being played at increasingly higher volume/groove modulation you can easily hear the result of mistracking. I use an old Shure ERA IV test record, but there are other test records available for this purpose.

If the antiskating is off, one channel will mistrack before the other. The breakup (notes becoming fuzzy or a distinct sibilant buzz will be clearly heard from that channel. If it is the right channel, it means that the stylus is losing contact first with the right groove and MORE antiskating is needed; if the left, then less antiskating. You can easily replay the tracks to hear the result of your adjustment. When both tracks are about even when it comes to mistracking, the stylus force has been balanced between the two channels.

In my own personal experience, I have found that much LESS antiskating compensation is needed that the rough guidelines supplied by arm manufacturers. Perhaps this is the result of the kind of cartridges I use (for at least the past 15 years I have only used cartridges with line contact styli). The point is, one cannot rely on rough guidelines merely based on tracking force.
Linnmaster,

With the test records I have, my cartridge, a Lyra Titan, cannot track the highest levels of modulation without some distortion. The channel that distorts first, is the one that is getting shortchanged on lateral force. With this method, I get to about the same place as I do just listening to music the way Doug Deacon suggests. It is just that this method is easier, quicker and one does not develop the same anxiety over trying to hear differences in setting (usually the harder one tries, the less one is able to hear).

I suppose the ideal antiskating bias will change over different diameters of the record, but, there is no way to set the bias for all conditions. In the ballpark is good enough. The people at VPI do not think bias setting is important enough to add extra mechanism that can vibrate and add a different form of vibration and so they left antiskating mechanisms off of their arm.
