Nestorovic Labs

We recently acquired some vintage audio: Nestorovic Labs 5AS Mark IV speakers and Nestorovic NA-1 high resolution tube power amplifiers. Upon hearing the speakers with our current 5-2-2 home theater configuration, we immediately promoted them to the front L&R positions where the Tekton SEAS Pendragons had been. The Tektons are incredible speakers but these Nestorovics surprised us with their sound. Now we're carefully exploring the NA-1 amplifiers, and honestly, I am more than a little intimidated. The amps have not been used for 10+ years and the tubes have a layer of dust on them. The goal now is to fire them up without making a mis-step that could damage the amp or speakers, judge the quality of output, and decide whether to keep or sell. Next step (I think) is hook up the amps and speakers to a CD player and a Schiit Sys for volume control. I have high expectations for the improvement with tube sound, but if there is a market for these anything close to the little bit of hype I've read about the NA-1 amps, I expect we'll sell them. It's possible their moment has passed, in which case we're on the path to tube hi-fi enthusiasm and falling into that rabbit hole. All comments are welcome as we either sell or fall in.
