ParagonCould make a solid argument for vacuum tubes in hifi having gone this path too.
Having played a small part in that resurrection of tubes, it is phenomenal how a few sparks and small campfires grew into essentially dominating high end amplifiers for the next 50 years!
In 1974 the Audio Research SP3a preamo was perched solidly in the kings chair destroying every SS preamp that anyone introduced including McIntosh, Levinson, SAE, GAS, ETC. I met Bruce Moore in the Dynaco Mods community where he had radically modified several PAS-3 preamps into contenders. I asked him a simple question: Why not start from scratch instead of being stifled by that small Dyna chassis?
His answer was quick; Sure, give me $100 bucks to defray the cost of the chassis and I'll build an Ultimate Preamp that will kill the SP3a.
I wrote the check immediately. He asked me, what do you want to call it? Paragon, i told him. Exactly one week later he invited me over to hear The Paragon. He had an Altec A7 system with no cabinets laid out on the bedroom carpet. I can't say much for the listening, but the preamp was a massively cool beast, including a fully hand lettered front panel.
The next few weeks was a blur of making the rounds to every audiophile we knew in the Bay Area. The Paragon killed it every where we took it. A rich gambling house owner said, "Make me three right away--I'll give you $1500." We diligently worked around the clock for week or so and brought the three to his casino where he popped the cash drawer and counted out the Benjamins. Bruce and I were punch drunk at that point.
One of those three units ended up at Sound Advice Magazine in San Francisco--unbeknownst to either of us. A month or so later, my phone rings. The publisher tells me, " The Paragon is our cover story for January. We had a big preamp shootout, and the Paragon was Cream of the Crop."
Before I knew it. I was building Paragons in my garage to send all over the world. Bruce decided not to join the chaos. I forged ahead for a tumultuous 4 years. We left a small mark in the Tube Renaissance. Boy oh boy, those were the days!
