At US$895, this Paragon System E tube pre-amp is a strong bargain, landing well below the 25th percentile of US$2,342 from your database of four recent USD listings, and far under the median of US$5,269. Even compared to external vintage tube preamp data showing used ranges like US$2,500–US$3,500 for similar-era units, this asking price is exceptionally low for a 1970s USA-made system with an outboard power supply.
The Paragon System E is well-regarded for its warm, musical tube sound and robust outboard power design, offering genuine sonic upside over integrated preamps. With the vtg 1970s origin and included vtg power supply, this represents a rare, original-owner opportunity at a price that makes it a clear buying opportunity for any tube enthusiast seeking vintage American hi-fi without the usual premium.
