A Good Choice to Enter the World of Tube Amps

Little Dot MKⅡ is equipped with SEPP single-ended push-pull circuit, which brings excellent output dynamic range and delicate sound quality performance. If you are just interested in tube amplifiers world, MKⅡ must be your first choice.

High-Profile Front-tube&Back-tube

The front tube adopts Dawn 6J1, which has a beautiful timbre and is outstanding for listening to human and female voices. The latter tube 6N6, a classic power tube, has the characteristics of high output signal voltage and low distortion.

With the enhanced version of the output circuit, the output impedance is reduced, and the load capacity is stronger. MKⅡ is not only a headphone amplifier, it can also be connected to the rear stage of the split power amplifier, as a pre-amplifier to improve the sound quality of the speaker system.

Good tube amp and good support by Linsoul

I bought this tube amp for my 6xx’s and 560s, when I had originally bought these I read a review that they were accidentally sent the wrong adapter/voltage model, so I reached out to support before my order had shipped and they made sure I got the US version, super nice and quick support. The tube amp is great but I switched the tubes for Riverstone’s which sound a lot better.

Great tube amp, not so great service from Linsoul.

I love the amp now that it is all working. Works and sounds really, really great with HD 6XX headphones. But it was a long process to get here. Linsoul sent me the 220v version instead of the 110v version and gave me the run around for weeks and weeks. They eventually, finally sent me a 110v to 220v step-up transformer so that I could use the amp with my USA electric outlets, so now everything is all good and the amp is great with higher impedance headphones like the HD 6XX or even the HD 58X. I did roll the tubes to customize the sound a little bit, but even the stock tubes that come with it are fine.
