Looking to pay the rent, a coworker sold me one of two he had back in the early '90s. The Nichicon bypass caps he'd added eventually began to leak so I had an authorized repair shop remove them and ensure everything was in spec.

When I got it back the magic was gone and I sold it. But I recall it possessing effortless ease and smooth sound and can understand why JGH liked it.
