Well Charles, I've just checked the main UK source of Dueland Cast PIO Copper caps, and depending on spec, they range in price from $300 to $3750. Gulp! I presume I need these for the preamp only? How many am I likely to need, just 2 with labour charge to install would cover the cost of a brand new Atma S30! Anyhow, I thought one of the big positives re Bob Hovland was that his Hov MusiCaps were great performers and sought after by other component designers.
Isn't this all a bit of a punt? I mean there's no way to a-b an upgraded amp/spkrs with caps installed against the unadulterated originals. This is almost as risky as a particular cartridge dealer in the UK refusing home trial, expecting me to buy without being totally secure in hearing it in my system.
Lack of comparison leaves me a little anxious re the outcome. I have to emphasise the Hovs only demonstrate a hint of glassiness on some material, and I'm still convinced this is eminently tolerable with the liquid neutrality I hear most of the time. Additionally, the 4s are changing for the better literally day to day, bringing much needed warmth to offset occas coolness. Still convinced careful cable/power cord choice (Zu Event), vibration control (settling on Symposium Isis and prob Minus K on wall shelf for tt) and balanced power overkill (Westwick Audio 8kVA transformer) will maximise neutrality with just the right amount of warmth to hopefully fully balance the final sound. But I'm not going to totally dismiss possible SET/OTL avenues.
