I had been running my original LS50's off my Carver M-1.5t power amp using only the analog out of my Bluesound Vault 2 as input source. Adding a Kenwood KD-4100 direct drive TT that I'd (mostly) resorted meant I had to break down and get a receiver or pre-amp of some kind. My son loaned me his Luxman R-351 but just like mine there's FM crosstalk coming through the phono stage.\n\nPicked up this Emotiva UPS-1 pre-amp off FB Marketplace from the original owner for $200. Truly MINT condition, everything but the box. The subwoofer control shocked me, both low-pass & high pass filters with crossover for each and both RCA and balanced sub outputs. My sub amp is a Dayton SPA250DSP and has balanced input should I ever want to try it.\n\nSounds really quite good! Wish there was capacitance loading for MC cartridges, but just a default. The MM side I'm using with the AT LS500 (Lab Series) cartridge is excellent and totally noise-free. Very happy!!\n\nHow dare you put this as an attachment. :p Put this in the vinyl thread!
