Used audiophile preamp


 I’m looking for a used  audiophile preamp either solid state or tube. Looking for recommendations. Prefer less than $4000. Currently own Jeff Rowland Consumate preamp, phonostage and power supply.  Older technology but still excellent. What does newer technology have to offer over what I have?  Soundstage? Musicality? My system includes Linn turntable, Odyssey Kismet monoblocks, Spatial M3 Turbo spkrs, Schitt DAC, Cambridge CD Turntable, PS Nuwave, etc.  Any recommendations would be greatly appreciated. All input welcome. Thanks.

I owned both ET5 and ET7 and in my opinion ET7 is a improvement over the ET5. In many ways there is no comparison. Improved clarity, dynamics, staging, imaging, and noise floor. Top end extension on ET7 really shines and is sweet. ET7 series 2 has a bit more refinement.
 Every CJ preamp has its charms!
