Upgrade SUT For Denon DL103

The Altec 4722 based MC step ups run particularly well with the Denon 103, better than the A23 in my view. Haven’t compared to the Homage though.

Also don’t underestimate the classic Denon S1 step up. Although I haven’t heard it, a super high end cartridge manufacturer recommended it for my cartridge in preference to their own.

You should also factor in interconnects between SUT and phono - they alter the sound hugely and experimentation is required to get the best results.

I have a much cheaper Jensen mc- 2rr -L, it was designed with the Denon 103 in mind. However, that Auditorium 23 SUT is known to be very nice. 

The 103 cartridge, unless modified, has a finite limit (like all cartridges) to it’s capacity for expressing nuance. the denon 103 is known for it’s self noise which blurs and covers up detail. That is why so many modified versions based on the 103 exist out there in the wild.

therefore, look to a new expression of a 103, a modified 103, an altered ’lower self noise’ version of a 103, and then you will get more from the Auditorium 23 SUT that you already have.

The OP might be using a modified 103 or a cart based upon a 103, already, but that is not clear from the OP itself.
