Dear @ibelchev: Obviously that you just don't read my posts here about why and from where came SUTs.
Ortofon mainly is a cartridge manufacturer not an audio electronics items. From its began Ortofon as all other LOMC cartridge manufacturers always joined its cartridges with its SUTs that they manufactured and they had to manufacturer SUTS because was the only alternative to listen those kind of cartridges in a " decent " way and not because was the SUT the perfect alternative. Was the only one on those old times.
Active high gain phonolinepreamps just did not exist in those times at least niot good designs.
Tubes are out of question for active high gain phono stages so normally almost all tube manufacturers use SUT, externally or internally to the design, because tubes has no other viable alternative and not because SUTs are better. Some SS phono stage manufacturers gone for SUTs because it's a lot more easy to design that way than an active alternative. You need very high knowledge level and skills to do it.
In the other side active high gain SS phonolinepreamp design is not an easy task but if the design and excecution to that design is a good one then this is the true and best alternative. I explain in my posts.
I'm not saying here or else where that SUTs are bad because are not but are inferior no matter what to a good SS active high gain stage.! ! ! Noise levels, distortions and very limited frequency response is where SUTs just can't compete.
Regards and enjoy the MUSIC NOT DISTORTIONS,
