Smooth Analogue Sound With Convenient Bluetooth

Compact Integrated Valve Amplifier
35 Watts Ultra Linear, 18 Watts Triode
Bluetooth 5.0, Headphone Output
Easy Onboard Valve Bias Adjustment

The Cayin MT-35MK2 BT Valve integrated amplifier takes over from the LA-34 and takes things to the next level. At its low price it offers a great place to start if you want to dip your toe into the world of valve amplification. The inclusion of Bluetooth and a headphone socket are very welcome additions. Designed and tuned in Germany. Proudly owned and manufactured in China by enthusiasts.

Although the MT-35MK2 BT is the entry into the comprehensive Cayin valve amplifier range, it has two great new convenience features missing from the earlier LA-34, the ability to stream music via Bluetooth 5.0 and the option to listen through headphones.

Valve/Tubre Rolling

Unlike transistor amps where the output transistors are soldered in, most valves are fitted to valve sockets, which allow the valve to be easily changed, either for a replacement, in the case of failure, or for a different type of valve. This practice of swapping valves to different models or different versions of the same valve is known as valve/tube rolling and allows you to fine tune the sound of the amplifier to your liking. Some of our customers have a host of valves they regularly change depending on their mood or the music they are playing. Of course you do need to be careful to only use the types of valves the manufacturer suggests – in the case of the MT-35MK2 BT you will find that the supplied EL34 Pentode Output Valves are available from many different manufacturer’s and interestingly they all sound a little different. Feel free to explore the opportunities.
