I had two dealers supply and leave me with 3 phono stages for just less than a week so I had a good chance to get to know them. I thought the uphorik was veiled, lacking in both detail or warmth. It didn't suit my tastes or system and was well short of the group. The Ios and diablo both fared a lot better and I rated them similarly though I loved the convenience of the IOS with a front adjustment. The Mcr reference was the best of that group, slightly costlier but good. Nice midrange but a little too much warmth for me and a little slow sounding. It was very good but for me not worth the £2k investment.
The leema Agena is in a different league IMO. Exceptionally transparent so it displays the differences in deck, arm and cartridge brilliantly. It has the convenience of the iOS plus two inputs with three headshell settings for each.
The bottom line though is that at this level a guess shouldn't be an option if you don't want to take a punt. Speak to good dealers and insist on home demo if available. You may adore the uphorick it just didn't do it for me.
