Hi Crimson and welcome to the forum.
What turntable and cartrdge do you use and do you have a separate phono stage?
Some Meridian processors (562, 861) have optional MM or MC phono cards/modules if you prefer the integrated/fewer boxes solution. Alternatively you could plug your phono stage of choice into a line-level analogue input on any Meridian processor. The A2D quality will vary by model from 16/44.1k (562) to 24/96 (depending which cards you have fitted) on the 861.
If you only have one analogue source, the line-level MP221 (now out of production) can do the job at 24/96.
I use the 562/MM card solution which, perhaps more by luck than judgement, works very well with a Roksan Corus Black cartridge.
