Solid state Accuphase, tube Atma-Sphere. If you need more tape loops, check out the Sony SB-500.
Best Preamp with Tape In and Tape Out Monitoring Capability
I enjoy Reel to Reel recording thus exploring options for preamps with tape in & out with monitoring. Would consider tube or solid state. My system is a Pass Labs XA25 amp, Pass Labs XA12 preamp ( no tape in / out) to Pure Audio Project Trio 15 Classic speakers.
