Voltage mode vs current mode phono stages

I think this is like many other things in audio. An allegedly "better" technology does not mean the listener will prefer it sonically and, as with everything, you need to try and see. I recently had a current-mode phono preamp for audition, but I much preferred a similarly-priced voltage-mode preamp, which was slightly noisier, but much better to my ears. Understanding the technology is fine, but it always comes back to the same old story. No getting around it, IMO.

Dover did not mention what current driven device he is using, so far as I can see.  However, he did say he feeds its output to the phono section of a Marantz 7 preamplifier.  That suggests he is using one of the very few available outboard devices that do the current to voltage conversion ahead of any conventional MM phono stage.  I think Sutherland makes such a device and a few others.  I think that's a great idea, as it does not require or may not require a major purchase cost for a whole new phono stage.  I am using such a device that was custom made for me, not commercially available. I use it only with the Ortofon MC2000 cartridge.  Output goes to a modified Silvaweld SWH550 phono stage in MM mode.  I have two other voltage driven phono stages that both have enough intrinsic MC gain for any of my other MC cartridges.

I did some reading on the van den Hul Grail.  The basic unit seems to be SE only.  The SB version costs nearly twice as much and provides balanced circuitry and some other unique features.  Depending upon whose review you read, the RIAA correction is done using either only inductors and resistors (LR type) or using capacitors along with LR (LCR).  Then there are the SE and SE+ versions that cost 3X as much as the base and include upgraded power supplies. I am not sure whether the base model (~$9000) has the fancy RIAA circuit or not. Fremer compared the base and the SE versions to the CH Precision with X1 PS.

@lewm , I think Fremer sleeps with his CH Precision. Nice unit but way more stuff than I need. I prefer simple.

I will be able to address this better in a while as I ordered a Channel D Seta L Plus which can be run either way. I plan to run it in current mode because of the theoretical advantage, the most important one is less interference with tracking. Every generator is also a motor. With less impedance this effect is more limited. 

@ledoux1238 , I think what you are hearing is a frequency response shift. Whether or not one is more or less accurate than the other is up for grabs. If I have two systems and turn the upper midrange and treble just 2 dB on one of them everyone listening will prefer the brighter unit even though it is "less accurate." In my own system I intentionally boost the bass because I feel it gives you more of the experience of a live performance even though it is "less accurate." This is why everyone has the right to listen to whatever they like. Unfortunately, that might make someone else cringe. My point is what a system sounds like is an extremely fast moving target. Interpreting what other people say is virtually impossible. There are characteristics which are more definable like those of the image. 

whereas voltage mode is an endless pursuit of SUT’s and loading. I have admittedly rather entry level stuff, so not the final word. 

@ledoux1238 If you have the right voltage mode phono section, its also plug and play- no SUT and no worries about loading.

@lewm 

Have you tried to drive a current mode phono stage with an SS LOMI?

While I have not, Peter explained to me that he is quite impressed with the results as long as suitable phono cables are utilized - something which I’ve often tried to emphasize.
