These are in my humble opinion, the best wideband high efficiency single driver speakers available. I have driven them with grand authority with as little power as 2.5 watt 2a3 amplifiers.
These speakers have about 3 months of use and barely broken in. The finish is metallic gun metal gray with rosewood side panels. As you can imagine from its age, the condition is like brand new but conservatively rated 9/10.
There have been several iterations of the Saadhana, this is the latest one with the NCore bass amplifier modules.
Unlike the overwhelming majority of other speakers catering to low powered tube amplification, this has (to my ears) no discernible compromises to lower frequencies.
It's been a dream to own these speakers; astonishing speed of rendition, visceral dynamics, nuanced articulation, tonal body, and effortless reach into the subterranean registers.
I may be willing to deliver to certain parts of California or equivalent distances from Northern Nevada.
