Keces Sphono und Sphono Power - Four In One Von Michael Vrzal @ Fidelity online (German)
"The Sphono is an excellent phono stage. It delivers a clear sound full of overtones, an outstanding soundstage and impressive effortlessness even with demanding recordings."

KECES Sphono Preamplifier and Sphono Power by Mark Pearson @
In summary, the KECES Sphono packs a lot of performance, features, and high sound quality that belies its price point in the market place. If you are one of the people who either have a table that accepts multiple arms or you have multiple tables, arms, and cartridges, I really don't know of any competition the Sphono has at $2600."

KECES Sphono and Spower by Dirk Sommer @
"Even owners of cartridges with higher internal resistance values, now loose all their arguments against the purchase of the Sphono, but win two weighty ones instead: its detailed, open sound full of enthusiasm and emotion, crowned by its still customer-friendly price-performance-ratio!"
