Blue Circle Audio is Out of Business

@has2be points well taken. I’m not an insider here, but know that Gilbert had thought of retiring for quite a while, and had alluded to it multiple times on the BC forum. I agree this was an abrupt end, but Gilbert retiring and the end of BC would have to coincide, unless he sold the name. Though I don’t know if there would be much interest in BC without Gilbert. Your question about in warranty repair is certainly valid, and I don’t want to respond without having a confident answer, which I don’t. At the time I posted I had heard that HE would honor repair and warranty work. You’re right, I hope BC owners get some answers.

Thank you for the respectful reply.

I am actually surprised that Gilbert was essentially a one man show for as long as he was. Not just the roller coaster economies through 3 decades, but the emotions the industry seems to bring out towards the non status quo in his time. I had a couple of his products before I went back to a complete tube based system, and also to one system. Zero complaints here for sound quality and reliability during my time with BC pieces and the new owner was elated to own them, and still does actually. I still own one of his earlier filters , BC 84 for Analog and Amplifiers . Actually does what it claims , and nothing more .

Warranty can be a real bone for the disenchanted to swing around and as has been seen before, the unrealistic and the petty have often embellished with one sided narratives using an IP address and some agenda as a weapon and a curtain to hide behind.
It’s for this reason I felt the closing was handled poorly and I hope full information is applied much sooner than later to avoid some of the eventual hear say , rumor and especially vitriol from the agenda driven types.
It’s all too common to see post’s on forums by some dolt who was not wronged, but simply didn’t get his own (usually unrealistic) way so any chance these dolts get to fill the web with negative waste to show up on searches, they do so. His products IMHO , were reliable , offered fine sound quality, fairly priced, and were all for the most part well received publicly . Realistically, I doubt there will be much need for IN warranty work with how reliable the products are and have been, but the mindset of knowing it’s there and the unknown can be problematic to many .
I’m in full agreement with you. I can clearly see why these events would be a bother to  BC owners, particularly newer ones. As much as I found his quirkiness and pursuit of staying off the beaten path appealing, I see how that wouldn’t work for many. His design approach, which seemed to be as driven by the “art” of amplifier design as engineering, was unique, but frankly too weird for most. It’s particularly unfortunate that things have ended here because his latest ($$$) designs were truly stunning, and among the best amps I’ve ever heard. But again, that same quirkiness has lead to this ending, which is not ideal.
