Ross Mantle of Audio BEAT just published this wonderful review of KR VA 910 mono amplifiers. This is an interesting write up about rather interesting amps as there is no other PP amp existing which with Max 160 W output given is capable to stay in pure Class A up to 120 Watts. Quite impressive. This article is especially interesting to me due to his use of Lansche Audio P- 5.1 speakers ,which are complete contrary to KSK stats used in the Sound Stage Ultra test.
Enjoy all the write up here and for final conclusion please read the summary quote below:
” If it’s not already obvious, I’m quite impressed with the VA910 monoblocks. The usual push-pull, four-tube amplifier has, in general, very pedestrian sonics compared to these from KR Audio. How in the world do they do it? These no-hassle tube monoblocks with XLR input just work. The incredibly accurate and emotionally involving sonics have the solid three-dimensionality, huge soundstage, and high resolution and transparency that I call the KR Audio house sound. They have that sound despite the fact that they are push-pull, class-AB amplifiers rather than SETs. They outclassed the more expensive Lamm M1.2s in a direct comparison. From memory, these KRs would also have beaten the much pricier solid-state Linn Klimax Solo monoblocks I used to own. Again from memory, my Joule Electra VZN220 OTL monoblocks were better in some ways, with more airiness and inner harmonic detail, but the Joule amps are impractical and finicky space heaters that require two power cords each and would be more than twice the price of the VA910s if they were still made, which they are not.
My final word is that the KR Audio VA910 monoblocks outclass more expensive competition both in price and performance with no fuss and a sense of high reliability. They are not what most would call inexpensive, but they offer world-class sound at something of a budget-conscious price. I cannot speak for everything on the market, but I would not be surprised to find that the VA910s surpass all comers at their power output and price.
But regardless of power and price, these are emotionally involving, superbly engineered, aesthetically understated monoblocks that are unconditionally compatible with all types of music — beauty and truth in equal parts.”
