All my preamps uave a different tone.
this is on 2ndary basement system
B&k pro10 mc is smooth with no harshness. Adds depth to midrange and is a nuthair bright.
sanders “preamp” is the cleanest nothing added straight wire w gain ive ever used
Very honest with recordings and bad is bad and great is great. amazing features, there is “zero” change in sound unless i set tone controls
onlyo P-308 adds an overall very natural low frequency tone to entire audio spectrum during playback it adds some lows to recordings which need it and does not cut off highs with playback midrange s more crunchy w p-308
When i switched to the b&k in mid late 90’s from onkyo tx-890 used as preamp for the m-504 and matching tuner/eq/sl-1200mkii tt. Jvc tape deck/wollensack 8 track.
tape and 8 trk have been cleaned wrapped and in storage in other room.
eq in closet. Havent really used in years.
i do need new rca intcts one of these days. The beldens are nice as are the gronberg ts premium.
when i bought and swapped the b&k pro10 for tfhe P-308 i was “wow” i like that.
sounded beefier. I use the Sanders now, i like the very natural and uncolored sound with many recordings.
