Little Dot Headphone Amplifier MKIV MK4

The Little Dot MKIV is the flagship headset amplifier of the brand.
It uses a Single Ended Push-Pull amplifier circuit in Class A based on JAN5654 tubes
These tubes are surrounded by quality components such as a potentiometer ALPS RK-27, capacitors Nichicon, Rubycon, WIMA, ERO ...

This amplifier can driver headphones from 32 to 600ohm without forcing thanks to its output capable of 45V peak-to-peak.
RCA outputs allow it to be used as a preamp by taking advantage of the Class A

In addition to this, this amp includes an externally accessible gain adjustment to best match the impedance of your headphones.
It is also possible to change the input tubes by EF92, CV131, WE403A / B, GE5654, M8100, CV4010, EF95, 6JI or compatible (Requires the addition of a jumper)

Je viens de recevoir mon MK IV ,ça fait 3 heures qu'il fonctionne,il "drive" un Grado sr 325 et...QUELLE CLAQUE!!! Le son est doux,détaillé mais en même temps on sent qu'il a de la pêche,pas d'agressivité au niveau des aigus,des médiums bien restitués et des basses bien sèches et profondes ,une bonne spacialisation bref que du bonheur et il n'est pas encore rôdé.
Un petit ampli à conseiller sans retenu.
