Silver rewired with Cardas clips, smooth sound and detail. Using a Mitchell VTA also, not on the fly but good enough if you plan to set and forget.
Audio-Technica USA AT-0C9 MLII
Excellent detail, a little analytical but very nice and can't be beat for the price.
Musical Surroundings Phonomena
A very flexible phono pre-amp that can match any cartridge. Maybe not the very best in phono sections but can't be beat at used prices.
Endler Audio 5 Input Passive
Silver wired, 5 input passive pre-amp with 24 step silver wired stepped attenuator. Exceptional detail and clarity if you can go passive.
First Watt Clone F3
Just enough power for a 97db horn. Sweet sounding low distortion amp paired with the 846b makes for a truly amazing sound for jazz, most rock and classical.
Altec Lansing 846b
Found second hand for a good price
Supra Ply 3.4
Great sounding cable at the most I'd pay per foot
DIY DNM Eichmann Bullet
Solid core, low mass, detailed and musical. If you are in a low RF environment get yourself some
Seems like a great system you have there. Two items I am intimately familiar with is the SP-10 mkII and the RB300! Your plinth even looks more-or-less just like mine.
