FOR SALE: KR Audio VA-340 Single Ended Integrated Amplifier
I have owned this amp effectively from new (see below) when I purchased it in 2010. It uses KR Audio's 300BXLS tubes which have about 1200 hours on them. The amp has been hardly used and is in excellent condition. The one fault, if you could call it that is that one of the LEDs that indicate the source selection is dimmer than the other 3 but as you only ever have one LED lit at any one time you hardly notice it.
History: This amp was bought from The Audiophile Club (http://www.theac.co.uk/) in late 2010 prior to my emigration to Belarus in 2011, the current location of this amp.
The Audiophile Club were the UK distributors for KR Audio back then and the amp was their demonstrator. Shortly after the purchase a tube developed a fault and 2 new 300 BXLS tubes were obtained directly from KR Audio under warranty and fitted.
So how come only 1200 hours in 7 years - sounds a bit fishy eh?
Well, to cut a very long story short, the inside of our newly built house was a total mess when we arrived in 2011 and needed a complete interior renovation - all interior walls, ceilings, electricity and plumbing. Understandably, I left all the audio equipment plus a lot more stuff in their boxes and kept them in (warm and dry) storage. After a delay of nearly 3 years in various courts suing the builders and winning compensation the renovation started and was finally finished last year. However; the listening room was completed 18 months ago and the hi-fi put into use while the work continued on the rest of the house as we had ensured the listening room would stay dust-free. That’s why there’s only, 1200 hours on the tubes!
So why am I selling?
Mains electricity is adversely affecting the sound here and I need to switch to equipment which does not suffer from this problem.
Where I lived before the 340 sounded great. I was blessed with a first class mains supply with any voltage deviation from 230 being above rather than below the 230v norm. In Belarus the voltage in the cities is a robust 220v but where I live (in the middle of a national park) it frequently drops to 216V and, more importantly, there is also a limit on the current that can be drawn. I didn’t realise this before I bought the 340 and I have recently and rather too late found out that this lower voltage means that the tube filament voltage may be too low. Apparently it is better to have an ‘over-voltage’ problem than the reverse regarding sound performance. This corresponds with my listening experience here which has been a disappointment compared to where I lived before. So, please bear in mind that you need a good 220v supply (and preferably a 230V supply) without any current limitation to get the best out this unit. Don’t use mains filters or even a re-generation unit both of which can limit current. If only I knew then what I know now! I found this recently in a 6moons review of the VA-340:
“ From previous KR Audio reviews, we knew how these amplifiers do not like power regulators or line filters. As a Class A design, the amplifier should not be restricted in getting enough juice from the wall outlet.”
I hope that answers any questions you might have about the unit. If not just contact me by email.
