You can't go wrong with RAM Labs Super Low Noise grade. These are very quiet and transparent and only 2% of tested tubes are graded Super Low Noise. The 12AU7 is difficult to find with low microphonics, especially with NOS tubes. I use Super Low Noise RAM tubes in all of my input and power tubes on my VTL and CAT electronics. Here is the website tubeaudiostore.com and I am not affiliated with them other than as a consumer with 30 years in this hobby.
need help on transparent sounding 12au7 tubes
Hi,
I'm currently using NOS RCA clear top 12au7 in my Audio Valve Eklipse preamp. Looking for a 12au7 that's more transparent, detailed, maybe higher resolution to try with this preamp. Not looking for a tubey sound. Thanks.
