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

Thanks everyone!
For what it's worth, I by no means am saying that just because two components are "placed in the same class" by Stereophile (or anyone reviewing anything for that matter) that they are equal.  IMHO reviewing is subjective by nature, we are all humans and opinions are part of who we are, part of our individual personalities.  What I am saying, however, is that I expect two components in the same class to perform comparably, not one being vastly superior to another, regardless of price.  Ortofon 2M Blue is placed in the same class as 2M Black by Stereophile.  Do they perform the same?  I don't know, I don't have a $1K to spare to find out.  I would expect not, given that 2M Black cost three times more than 2M Blue.  I have a friend who own a 2M Blue and loves it.  He is about to upgrade to 2M Bronze and will loan me the 2M Blue to try out in my rig.  Then I will be able to directly compare 2M Red to 2M Blue in my rig, on my terms.  And I will not say anything to myself or others about 2M Black because - guess what? - I have not heard it!
@jperry  - Thanks!  Synergy indeed is what really matters.

Happy listening!

Why do you need a SUT with the Pro-Ject Tube Box? Don’t you have enough gain without needing a SUT?

@yogiboy - There is enough gain on the highest setting - 60db on Tube Box to make it work, but anyone who dealt with DL-103 will tell you that to extract most performance out of it you need a SUT, preferably the one designed specifically for a low output MC cart, which DL-103 is. A23 makes a couple of SUTs, and reviewer in the article linked below had reason to beleive that A23 DL-103 SUT (at least to some degree) was voiced around the namesake cartridge itself.  I will also be trying a new phonostage in the near future, Bob Sachs, that is well known to get along great with DL-103 with a proper SUT.  Happy listening!

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.

@billwojo So, simply increasing the downforce will not acheive same effect?  I was planning on researching and using Nasotec Swing headshell, which weighs 11.5 grams.  18 grams is a lot!  Thoughts?  Link below:
