DL-103 + A23 SUT + Pro-Ject Tube Box DS = ?

I plan on trying my newly modded by Zu DL-103 here pretty soon.  I have an Auditorium 23 SUT and Pro-Ject Tube Box DS is my phono stage (unmodified, stock tubes). I know, I am broke right now.  What settings should I use on the phono stage?

Pioneer PLX-1000/DL-103 --> A23 SUT --> Pro-Ject Tube Box DS --> Cary SLP-05 preamp via Acoustic Zen Wow! II RCAs

Here is a link to it's manual with jumper settings, etc:

Most SUT's are expecting to see 47K ohm loading at the phono preamp so I would go with that. As far as capacitance I don't think it's near as important as a MM cart so set it at about 200pf and see how it sounds.That A23 is VERY nice, my buddy uses one for his DL-103 cart on his Garrard 401. Sounds very good into his Shindo phono preamp.
I'm using a Denon AU-320 for my DL-103 and am happy with that as well but if the right deal came along on a A23...........

Not at all. I don't think I'd waste my money on that Nasotec. Not every gram of mass added to the headshell adds to the effective mass either, it's not as simple as EF mass = 12 Grams and a 10 Gram headshell = 22 grams of EF.
I would use as heavy a headshell as you can find and add some weight to the counter balance. It will help some.I'm using a Audio Technica AT-LH18H for my headshell on the ATP-12T tonearm.
There have been some lengthy discussions on this board about EM.

The A23 designed for the DL-103 is a hard combination to beat. If I had the money I'd have one myself but I'm pretty satisfied with my Denon AU-320. It to was designed to work well with the DL-103 cart. The other thing about SUT's that I found is they are dead silent if setup properly. If you get hum or other noise, there are problems going on.I have to agree with Chakster about the tonearm, those Denons really like a heavy arm. It will work on your arm but you are giving a lot up. Do some reading on this.
It's why my TT project has a Audio Technica ATP-12T arm mounted in the back position. Effective mass of 21 grams and I plan to use a 18 gram headshell on it as well. Those carts were built for heavy broadcast arms.
