I learn about any interesting audio equipment solely through reviews from magazines, the internet, or YouTube videos. Over the years, I have purchased a very good system. The speakers, not listed, are the only items I would not buy without hearing them first. The first time I listened to any of the electronics was in my home after the purchase based on what I had learned.
Denafrips Gaia DDC
Denefrips Terminator Dac
PS Audio BHK Signature Pre Amplifier (tubed input stage)
Pass Labs X260.8 Mono Amplifiers (2)
Sony Blu Ray UBP-X800 CD/Blu Ray Player
Every piece listed above did exactly what I was looking for and expected based solely on the information sources I used. I do not care how, why, or what alleged gains these writers received; their opinions were truthful and helpful. Since I live in an audio wasteland state, Oklahoma, they were my only source of enlightenment.
