What cartridges under $800 outperform DL-103R?


I have a brass plate on my nude DL-103 and I'm ready for a change. I'm looking for more air and ambiance, but don't want to sacrifice extension on either end.

I'm debating whether to try Uwe's Panzerholz body on a 103R, or try something altogether different like a Dynavector 20XH, Sumiko Blackbird, Lyra Dorian, Zyx R50 Bloom. I had a Benz Glider L2 (0.4 mV) for a while, but didn't find it any better than the 103R. My tonearm is Micro Seiki MA-707.

Any insights or suggestions would be greatly appreciated.

Second the recommendation for the Audio Technica AT33PTG. I've been able to listen to both this cart and the 103 in the same TT (Scheu Premier MkII/Scheu Cantus) and the 33PTG got my vote easily.
I own both a stock Denon 103R and a Zyx Bloom (.48). They're both pretty good and I'm not sure I could call either one better overall. The 103R has great extension at both extremes, but the highs are a little more etched and the bass just slightly fat. The mids are fabulous and the detail is more than adequate throughout the range. The conical stylus makes it very easy to set up, since it's not real sensitive to misalignment, but also makes it noisier in the groove.

The Zyx is more refined and tighter within its range and has better detail than the 103R, but doesn't have that real magic in the mids. It needs far more careful alignment, but is WAY quieter in the groove once it's dialed in. When I bought it, I didn't have as much phono gain as I have now, so I got the higher output version. The .24 version might be a little different - I'm sure Mehran could describe both for you.

That brings up the final point. While the Denon has 40-50 years of Denon research and refinement behind it, the Zyxs have Mehran, at least here in the US. He's a pleasure to work with, and a true gentleman.

I fear your experience with the cartridges you're considering may be the same as with the Benz you tried - while they may all be different from the 103R, they may not be noticeably "better".

I own a 103R. I also recently sold my ZYX Airy 3. While the Airy 3 was better, especially tonally, I don't think it was as much as you'd expect given the price difference. My opinion is the 103R is a great cartridge that belies it's price, as opposed to the reverse. I owned a Shelter 501MkII that I liked as much or better than the 103R. I also just bought a Shelter 901 for $600 with the top shelf Soundsmith modifications (3 levels available on their website for your 103R or buy one already moidifed- That should tell you what Peter Lendermann thinks of them) but I've not had a chance to mount it yet.
Most are unfamiliar with the Denon DL-S1 for about a $1000 probably available for $800. I have to say honestly I have not done a direct comparison and only have a menoty of the 103R. My sense is the top Denon does most everything better and opinions available rate it a true value in high end cartridges. I'm not sure what best is since all have plus's and minus's. In my really high end system I have settled on the DL-S1 as a real world cartridge that does as well as anything else I have heard even remotely close in price. Zu does Denon mods and I have called and pleaded with the designer to work his magic on the DL-S1. He says he has thought of it and wants to try. If he does, I'll probably buy one on the strength of the two.

Feel free to ask me any questions, I'll try to answer honestly.
