Exzellente Phonovorstufe (MM/MC anpassbar mit Minischaltern) für Verstärker ohne Phono oder als Upgrade zu einem suboptimalen Phonozweig preiswerterer Vollverstärker. Bei meinem Roksan spielen beide Phonos auf Augenhöhe und so reduziere ich ein wenig Kabelsalat und biete die Pro-Ject hier an. Anstelle des Steckernetzteils hat der Vorbesitzer ein verstärktes Netzteil als Upgrade angeschafft...Die EH Röhren habe ich NOS aus meinem Bestand vor einem halben Jahr ersetzt.

Very nice lightly used Pro-Ject Tube Box S2 with upgraded Telefunken reissue tubes. Great warm phono preamp for any decent vinyl setup. Ill also throw in a very nice set of SKW RCA 1-meter cables. Tube Box S2 is Pro-Jects very first product to feature a fully discreet circuit design without using any operational amplifiers (OpAmps). It also is the first product to come with replaceable tubes for tube rolling and sound-shaping. This provides the listener many options to pick from and gives them the ability to alter the sound signature to his/her preference. Tube Box S2 will give a full and relaxed laid back sound with lush mids, just like you would expect it from a much bigger high end tube phono pre-amplifier. It offers support for both MM and MC cartridges and comes with many gain settings that can be switched via the front panel. Five variable input impedance settings are available to adjust to any MM cartridge, while the 47k ohms input impedance setting is fixed and suited for high output MC cartridges. The aluminum/metal casing is adapted to the DS2 line in looks and protects against vibrations and electromagnetic interferences for superior sound.
