Jeff Rowland preamp phono better than dynavector?


I'm pretty new at high end audio, so this might be a stupid question, but here goes.

I'm currently using a Dynavector P75 phono stage and a Dynavector 20xMC low output cartridge on a VPI Scout TT. I really like this cartridge and want to stay with the low output MC. But the step-up transformer runs through an old McIntosh C-28 preamp, so it seems to me like I'm basically just bypassing the pre-amp, which isn't a great one anyway. So I'm considering getting rid of the Mac preamp and the phono stage and buying a Jeff Rowland Consonance with a built-in MC phono stage. Can I expect better sound by getting rid of the Mac/Dynavector combo and replacing it with the Consonance? I should add that I pretty much only listen to LPs, but I would like to be able to run a CD player through the preamp, too, at some point.

Thanks in advance for any comments.

I have used both of these, being a dealer for both. I think you are confused about the nature of the 75 as you are calling it a step up transformer. A SUT is used in front of a phono stage for very low output cartridges. For example, I have used a Bob's Devices SUT with the 75. I assume you are running the 75 into an AUX input on the C-28 and not the phono input, if you are do not do so. There are several things you can do, I am not a fan of Mac of this vintage so I would change that.You can get a Passive pre amp which would work with many amps, you can get a better line stage and keep the 75 or replace it with the Consonance. If I had a chance to get the Consonance at a good price I would get it and sell the Mac. I would keep the 75 for a while and compare it to the JRs built in phono stage. If the built in one was better or equal I would sell the 75, if the 75 was better [I suspect it will be] I would use it and use the JR as a line stage. Or you could get an entirely different line stage. In any case removing the Mac will improve your sound.
Thanks, Stanwal. You're right - I was confused about what the P-75 does. And I am running the P-75 into one of the high level inputs -- one of the "tape" inputs -- and not into the low input MM phono input. Does it matter which high level input I use, for now?

I'm not married to the Rowland preamp, but there is one listed here on Audiogon for $1100. What I want is a good preamp that has a built-in MC phono stage that will at least equal if not better the P-75. I'd like to pay between $1000 and $1500 used. If it helps as a reference point, I do like the sound of the P-75 a lot, but I'd like a better linestage than the Mac C-28, and I wouldn't mind moving away from the separate phono stage. Thanks for any suggestions you all can offer.
single tranformerless phonostage is much more superior than the one with step-up tranny. Phonostage inside Jeff Rowland preamp is sufficient upto .2mV cartridges without any step-up device and it's a good price.
