I had the Croft Super Micro preamp with wonderful phonostage. Very simple and affordable preamp that sounded wonderful with my McIntosh MC30 and Marantz 8b amplifiers and Spendor 2/3 and then Altec 604E speakers. Tried different affordable preamplifiers and phonostages, but Croft Super Micro was the best match to my system that time. I really enjoyed this sound for 5 years.
Thank you Glenn Croft! R.I.P.
