I’m done. Really! Mainly because I’m 86 years old and my ears, while still fine without hearing aids, realistically cannot appreciate music details the way 20 year old ears can. But also because I splurged a lot to make my system complete in 2024. I bought a Luxman CL-38uC tube preamp and a Luxman MQ-88uC tube amplifier to become the perfect match for my Quad ESL-63 US Monitor electrostatic speakers. I bought an Ayre DX-5 DSD SACD player. I had my Bang & Olufsen Beogram 4004 turntable completely restored. I had my Nakamichi Dr-1 cassette deck completely restored. I bought Iconoclast power cables to replace my stock power cables so that all my power cables are precisely produced to a length that will keep them off the floor and from crossing one another. If I were so inclined to spend more money, which I am not, I would buy some sort of power conditioner, but I really don’t feel the need to do more. For the curious, my other sources are all dedicated to streaming, a Roon Nucleus, an Audio Alchemy DMP-1 Media Player Roon Ready and a Berkeley Audio DAC Reference Series 2 (I do wish I could afford to go to the Series 3.)
My system sounds great to me and I don’t feel the need to do more except to sit back and listen. And enjoy, of course!
