Qualiton/Audio Hungary

A Class-A integrated vacuum tube amplifier with an output power of 2 x 50 W. The A50i can be connected to 4 Ω and 8 Ω nominal impedance speakers. The power outputs, based on output pentodes type KT 120, were tuned to the before-mentioned nominal loads through our in-house manufactured, precision winding output transformers. The bias control circuit plays an important role in the operation of the power output too. This curcuit monitors the quiescent current of the output tubes and adjusts it to a preset value. Thus, all four output tubes are in perfectly equal operation states.

Out of three asymmetric and one symmetric inputs, one can choose the desired one using the front panel volume control and input selector rotary switch. The symmetric input features a mini XLR connector. In this case too, the entire volume control and input selector unit is in full harmony with the shiny polished casing of the appliance, bringing together functionality and aesthetics perfectly.

The clearly arranged, minimalistic remote control was designed with this philosophy as well: the unique and aesthetical exterior design was always kept in mind and the usability was improved. Finally, a couple of words on the set of tubes we use: the audio signal arriving on the selected input of the appliance is received by vacuum tubes type ECC83. The driving voltage as well as its matching are produced by E88CC/6922s. In power output, the before-mentioned output pentodes KT 120 are in action—strictly in Class-A. Sound?

Some Tube amplifiers use tubes for tubes sake, which is to say that making the amp sound like "tube Sound" is the goal.

The A50i and the rest of Qualiton's offerings utilize tubes to attain the proper balance of resolution,detail warmth and dynamics .In this They suceed and then some. Magical reproduction on a muggles budget.

I am deadly serious when I say that I have been longing for someone to create a power amp with resolution and grACE THAT SELL FOR UNDER $5000.00 TO MATCH SOME OF THE OUTSTANDING  SUB 7K TUBE PREAMPS THAT BACKERT AND ROGUE MAKE . THE QUALITON APX 200 MEETS THIS QUALIFICATION AND THEN SOME FAETURING A SELECTABLE VOLUME CONTROL THE 100 W PER CHANNEL A 200X SIMPLY WIBES THE FLOOR WITH ANY TUBE POWER AMP I HAVE HEARD IN THE SUB 10K RANGE A NO BRAINER FROM THE W0ORLD OF PLAINKI AND GOULASH.TOP RECOMMENDATION

The Qualiton X 200 defies simple description. It is all at once an integrated amp, a power amplifier, and a pre-amplifier. it even has tone controls which suddenly affect bass and treble when you use them or otherwise completely transparent. All of these features would be simply meaningless if the sound wasn't there to match them. But it is there. It is there in spades. We have never heard a tube power amplifier/integrated amplifier that sounds as transparent dynamic and detailed as the X 200 for anywhere near its price range. It absolutely trounces amps which we have compared it to that sell for 15,000, 20,000 even $30,000. But the Qualiton can be had for a mere $6500 which makes it our go to Tube integrated/Poweramp under $15,000. it even has an MM phono stage.A great one at that. with 100 W per channel There are a few speakers which it cannot drive. Put it on a pair of Harbeth HL5XD and you will hear Nirvana.
