These KR Audio VA910 mono bocks are from a trade-in in good conditions. A few scratches around, nothing serious. Voltage is switchable between 115V and 230V. They come with tube cage, a full set (8pcs.) of KT150 tubes and Beeswax fuses, double boxed.
These monos are very powerful (160W per channel) and can drive every speaker, even those with very low sensitivity (like electrostats).
Here's a couple of opinions from the press:
Jason Victor Serinus, Stereophile, Newport Beach Show (June 2015):
"...how's this for wedging $343,000 worth of equipment into a small space? Yes, everything and its mother began to resonate as Beverly Sills sang the famed aria from Korngold's Die Tote Stadt at high volume, but her top notes sounded so amazingly gorgeous, pure and warm that the experience was heavenly. This due in no small part to the touch of tube sweetness imparted by KR Audio's VA910 monoblocks ($16,500/pair) and P-130 MC preamp with phono ($6400)." Check out the entire article
Michael Wright of UltraAudio.com (Oct. 2013)
"...the VA910s’ sound exuded openness, detail, and uncanny realism. Their ability to draw me into the music and let me enjoy what the performers were trying to share with me was captivating... tonal colors were full and vibrant. The KRAs captured a good amount of detail and information about the recorded event, but in a way that made me want to listen to music and not be concerned with writing a review. The sense of soundstaging and scale was way above average -- the entire front half of my listening room was turned into an enormous soundstage filled with music... I could clearly picture the performers on the stage -- images had dimensionality, and air between them..." Check out the entire review
