Hi Myles, thanks for sharing that great video. In the mid 90's, I was visiting Hong Kong was stopping by some hifi shops there, looking for vinyl. I walked into a very small shop and they had a couple of bins of records. There were no other customers, but the owner of the shop was in deep conversation with an elderly couple. They then started playing a couple of nondescript bookshelf speakers and I was totally floored by the sound. I had to stop and walk the few feet to the front of the shop and sat mesmerized by the sense of realism of the sound. I found out that the visitors were Riccardo and Eunice Kron and I chatted with them. They were demonstrating an early version of their KR 300B tube- the biggest tube I had ever seen. I found out that the SET amp they had brought with them was over $20K, but I was hooked. Many years later I was able to finally fulfill, much more cheaply, my quest for a SET amp - not a 300B, but the Cary 2A3 monoblocks, which I still use with my Avantgarde Duos. In fact it was the SET amp that drove me to find speakers efficient enough for them. In fact, the Carys came with KR 2A3 tubes. After the first pair of tubes wore out, I replaced them with another pair - I think they were about $500 for the pair. When they went up to about $800 a pair, I switched to the Shuguang Black Treasure 2A3's which are the closest to the sound of the KR tubes, at almost half the cost. A few years after meeting the Kron's I read that Riccardo had passed away in the early 2000's. A couple of years later, I bought a used pair of 2A3 amps - the Bottlehead Paraglows, which I also have kept. This was my introduction to Bottlehead, many years before I met Dan and the TP.
Thanks, Larry
