nice setup. that tube box s2 is real nice, and that exact is a good cart.
for recommendation, i cant say whats best for you, but u could do what i did.
imagine ur endgame cartridge(s). hunt for a table thatll run it/them real nice. for me, it was hana ML, thats as far as id go, so i got a p3.
i should have gotten the p6, buuuuut...it was just too much money at the time. buuuuut also, i dont need a foam plinth anyways. im okay with the MDF. of i need to increase performance and SQ there are so, so many ways.
the rest of my system is totally different, but i did audition that tube box s2, and man it was nice. it was the only one of three i was auditioning at the time (ifi zen, s2, rega fono) that was a noticeable improvement over the onboard phono in my marantz 2325/2275 (i forget which one). had friends and family over, and they all heard an improvement. so nice job on the s2. rumble filter is nice.
why is that s2 on backorder? you can get it in 1-2 days from amazon same price as 2 years ago.
