Dma-300rs
- Thread starter mauidan
- Start date
It's out; dealers are being sent their units; orders have been accepted as of early March.
I finally decided that as good as the DMA 260 is, it will never be a RS, which is better in every way. Instead of buying the DMA 400 RS's, I bought a DMA 300 RS and a DMC 30 SV, which people seem to be drooling about, but I have never heard. Of course this also means an improvement in speaker wire from Matrix ML 90 to Oracle HD90 Rev 2 bi-wire with banana's. As the price increment for the improvement settles, I must admit that I have quite a bit of anticipatory excitement.
Congratulations; they are sensational products and probably a very significant step up. Would be interesting to see what you think about it all and especially of the cables and that 2C3D thing, which I totally despise.
I too am very excited although this change does not come inexpensively. I am particularly excited about the preamp. I should have both by the end of the month. I will also be happy to get rid of the SL Matrix 90, which is just not right.
I'll get you salivating... I heard the 300RS/30SV driving the Q1, to full orchestral swing, and it was really staggering, save for the slight tweeter coloration that I really don't like in that speaker. Then another time driving the Q3 or Q5 (can't recall), and the sense of presence/you are there was uncanny. A month will go by quickly. And yes, the SL cables are not as good a cable, and unnecessarily expensive for what they are.
I will keep you posted. BTW also bought about a month ago a VPI Prime, SDS (which truly made a huge difference) a Benz Micro LPS and Pass Phono Preamp. They sit on a Vibraplane and are amazing. I love the adjustable VTA on the fly. The 3D printed tonearm is wonderful.
Yes I read about your VPI - very nice. So here's a nice tweak you can also easily make, which I just implemented. Call up MusicDirect and order the "HRX pulley upgrade", which is the pulley they also use in the Avenger, and two more belts (the HRX pulley is not tapered like the one you have). This "upgrade" if you will does require that you have an SDS, which you do, so you are good (the groove depth is larger in it, thus speed is slightly different with what you have). The result is much more accurate speed (and I have measured it). Lead time, however, is about 6-8 weeks.
There are a couple of reasons why this tweak works, and one of them is that the pulley you have fits loosely on the motor shaft and is secured via three set screws - if you don't get it right, the pulley wobbles ever so slightly. The HRX pulley is manufactured to much tighter tolerances and you have to shove it down hard on the shaft (then secure it with its own two opposing set screws, but it doesn't matter if you don't, the fit is that tight). The other reason you get better speed accuracy is because of lower micro-flexing amongst all three belts vs one. The downside, one may argue, is more noise from the motor to the platter, but I am not hearing any. A further upgrade may be a Kapton belt (45 or 46 inches circumference), but I have yet to try it, and it does require that the HRX pulley be fitted with some sort of "guide" on the bottom (like a rubber band??) to make sure the belt doesn't fall off due to gravity.

I am not sure how to best answer that but there is more drama with analog, so perhaps the answer is yes, in my case.
Bonzo -
you just need to buy my 360s and your quest will be over once and for all!
They are on my top two shortlist with ypsilon hybrids. Thing is to figure it out needs time
Unfortunately just found out that my amp will take 14 weeks to arrive, but the preamp will arrive in the first week of February. Oh well. Time to get the new speaker wire broken in! Hopefully after this I will take a rest on new acquisitions.
It is July 16 and I just got my DMA 300RS today, but it was clearly worth the wait, especially when paired with the DMC 30 SV.
Dan,
I love it already despite the significant cost difference since I got only $4500 for the 260, but it is worth it and probably will get better in several days. Don't compare them if you are not ready to buy!!!
I just started a new thread about the 260 compared to the 300RS and the SDR 4000SL compared to the SDR 4000 SV-The SV Difference---which I think you might find thought provoking.
