Best preamp for atma sphere m60 under $3000 used?


I considered the mp3 and the mp1, one is too expensive the other I will always wonder if I can do better. What preamp will bring me over the top?
I make my purchases very carefully and rarely sell anything, the m60 will not be going anywhere, and I would like to choose a preamp that I can do the same, hold onto for a long long time.
It needs to be balanced and with tubes. Also from a company that has a good reputation. I would welcome a remote too.

Best preamp is usually no preamp:>

Irrespective of the budget, try the Placette passive. The closest to an attenuator without coloring the signal.

No relationship to the vendor!

Jeff Rowland Capri might work here. However, I have heard the M60s with the MP3 and the combination was excellent. Might be worth sticking with Atma for synergy.
The Atma's are not sensitive enough IMHO for passives with typical sources, maybe with very sensitive speakers. I found it did not work so great for me with the Merlins). I think the MP-3 (w/Vac and Power Upgrade) with the M-60s sound better than the Dodd Battey Pre and Joule LA-150MKI which I did try with the M-60s. You will never stop thinking there is something better out there, there is, but this combination should really get you off the merry-go-round if you are ready to. You would continue to use an ecternal phono pre, right?
Thanks all for helping out.
regarding phono stages I already own three and would welcome atma' phono for comparison and options.
