Analog Upgrade itch

If the DS Optical Generator is available, the buying into the DS Audio Cartridge Line is not too expensive.

I have listened to DS Audio Cartridges and SPU's in very different systems, I recollect the SPU on all systems it has been encountered, as a Rich Presenting Cart' and the perceived level is more than I am liking on the systems it has been heard used in.

I have only heard from my recollections a DS Audio 'Upper Range' Cart used on one system that I am quite familiar with, I have no recollections of detecting anything not to like about the Cart' in use. I do recollect follow up MC Cart's were more favourable and noticeably more of a attraction.

These Demo's are in non-owned systems and for were a short duration, any comments are from a recollection of a initial impression that has been made.   

This is not a criticism, just a observation of a trait that has been shared about your latest Phonostage acquisition. In Your Post it is stated,

" overall means it’s not overly coloured like some tube phonos but it has the density and 3-D holographic quality with excellent tonal balance and micro dynamics like some European phonos 2x the price "

I use Tube Designs that are towards the Lean Side in their presentation, I can add an increased Rich Tone through a use of a SUT. I use a Cart' that works with maintaining this attractive trait.

I can add a overbearingly Rich Tone by using a owned LOMC through the MM Input, it is certainly not to my taste, but is a achievable experience, with the Volume Maxxed Out . 

I'm confident the SPU is able to make the inherent Rich Tone become quiet noticeable, is this the desired outcome, to add Richness to a Phon' that is selected for it not having a too Rich Trait in how it presents.

I would think a Cart' that enhances the trait that caught your attention might be a alternative way to think about marrying a Cart'>Phon.
