Spark / Cayin 800
With four Russian 829B power tubes each, the power amps have an unusual tube configuration that allows them to realize an unusual 100 watts of power per channel for a tube amp. These power amps really drive any speaker, even impedance critical ones, and still deliver the unique fascination of really high-end tube sound.

Remarks[edit]
- Fortunately, replacement is not a problem with these tubes, as so much of this highly reliable military tube was produced that it should not be a problem to find NOS tubes should the need arise.

Reviews[edit]
I ran the power amps in comparison for some time with my Jeff Rowland 9TiHC mono power amps (65,000 euros). It took me a long time to decide to sell the Cayin again and keep the Jeff Rowland. In terms of musicality, voice reproduction and harmony of the music, this tube is clearly superior to my transistors.
