Suggestions for phono preamp for LOMC's

Nothing wrong with a gold note consideration. Can always upgrade it with separate PS. Lots of options also on the fly. 

I use a PS Audio Stellar phone pre with an Ortofon Quintet Black cartridge on a Technics SL-1200G TT.  I’m quite happy with that combination.  I may upgrade to a better cartridge, but I have no intention of changing my phono pre or TT.

PS Audio has a very good 30 day return policy. The Music Room has used ones for $1,899.  

I’ve used the Manley Chinook with my Sumiko Blackbird Lo with great results. It has very dark background and very adjustable. I have the same tubes it came with when I purchased it new in 2018 and no desire to change them out, still sounds really nice. 

I suggest you look at the Lounge Audio LCR MKIII Gold with their Silver step-up amp for MC cartridges.  That combo would be a bit under $1500.  I have the MKIII Gold with a MM cartridge, and the SQ is simply stunning, especially when I spin one of my 1980s Sheffield LPs or one of my 45 rpm LPs from that time.  Hand made right here in the USA, in the Los Angeles area.

McIntosh MP100 Phono Preamp offers Moving Coil and Moving Magnet adjustable loading (6 settings each); balanced and unbalanced analog outputs; optical, coax and USB digital outputs; and a Mono switch for playing mono records to decrease noise and play the signal correctly.
