I've gone down a similar journey over the past couple of years, and I can clearly
see analog becoming a deep, deep money pit to get to where it sounds as it
should.
My rig already costs $4k+ with table/cart, phono, cabling, set-up tools, cleaning
supplies, etc., and it's very good...sometimes better than CDs, but it has a long
way to go before it sounds as it should, IMO.
Never say never, but I'd like to stop here with the vinyl rig. I simply don't have
the LPs to warrant the expense, and inexpensive vinyl has proven to be worth
the money spent...i.e., not very much. Lots of surface noise/damage to the
gooves. I'd say maybe 20% of the used vinyl I have purchased is of high enough
quality to replace CD (or SACD, or DVD-A).
