What customers are saying about the L3 EL84 Triple C-core Amplifier Kit

Hi Brian,

I found ANK website by chance and was very interested. After having a talk to Brian on options for kit beginners we decided on giving the L3 EL84 a try. I got the kit finished over Christmas holidays and it worked immediately. That wasn't the big surprise though, the big surprise was how good it sounded!! Its so sweet , especially strings and vocals. Just a joy to listen to. I could wax lyrical with audiophile speak now. Lets cut that out and just say it has made my other amps that cost many many times more redundant now!!

The EL84 is a smaller tube and that does come across when compared to my 300B and 845 tube amps. You don't get quite the midrange presence but I absolutely prefer to listen to the EL84 for its better balance across the Hz range and sweet sparkle. The NOS EL84 tubes are also lot better priced than the bigger tubes as well so you can add some icing to the cake without getting another mortgage on the house....

My speakers are Sensitivity: 87dB/1W/1m and it drives them to very respectable listening levels. Everybody should have one of these amps in the audio arsenal. I think you will find it gets a lot of use like mine ..................

My audio buddies say its the best amp they have heard in my system and I have never listened so much as now.
