Can’t single out any one but here are the biggest winners for me, all current:
1) Ohm Walsh Speakers
2) KEF meta speakers
3) Roon
4) Cambridge Audio Evo 150
5) Room Equalization Wizard (REW) freeware (used with Roon DSP)
6) dbpoweramp for ripping CDs and Picard freeware to help with autotagging
7) Linn Axis turntable with Denon dl103R cartridge.
8) Audacity freeware to master analog vinyl converted to digital. This enables me to do my own digital mastering when converting vinyl to digital to then add to my digital music library and access via Roon.
9) Humminguru Ultrasonic record cleaner to get records spiffy clean before playing and typically also converting to digital.
Search my posts over the years and you should find I’ve elaborated on each of these at some point.
