 “ The APR 204 Mk2's impressive sonic shape shifting abilities elevates this pre above the 'typical norm'. It is not easy to clearly stand out in the big audiophile products crowd, yet Audio Hungary pulled the rabbit out of the hat with this preamp. For its asking price, the APR 204 offers a heck a lot of density and gain purity, and brought a big smile to my face. It always feels good when something is done properly, and in this case, is also priced more than properly"

APR 204 Mk2


Class A all tube Preamplifier with MM Phono Stage

The APR 204 offers three unbalanced RCA line level inputs as well as one MM phono input. With the help of the audio source selector switch at the front panel, the user can determine, out of these four audio sources, which one of the relay-switched, volume-controlled signal should reach the output RCA and XLR connectors.


If the input selector unit is in ‘P’, i.e. PHONO position, the signal to be processed gets on the grid of the first voltage-amplifying vacuum tube through RCA connectors marked PHONO - thus, through the shortest possible signal paths.


From here, in the before-mentioned classic way, the signal component gets on the grid of the second voltage-amplifying stage through a passive correction network between stages according to RIAA standard, realised exclusively with passive elements.


We use double triodes ECC83/12AX7 both in the first and in the second voltage-amplifying stage . Through an appropriate tuning circuit and volume control potentiometer, the output of the PHONO stage is connected to the LINE stage, consisting of E88CC/6922 double triodes.

The APR 204 Mk2 comes with an aluminum hand-held Remote that controls volume level and input selection.
