PRO-JECT TUBE BOX DS PREAMP.Solid Pre Amp. Tubes were replaced with Genalex 12AX7 Gold Lions a few years back. Sound great. Comes with original box and accessories. Sold all of my audio equipment and no longer need this.

Pro-Ject Phono box DS2 - Premium class phono preamplifier with MM & MC. Opened, unused. RRP: 329

Pro-Ject Phono Box DS Black Preamplifier for MM & MC Pickup. This is a very versatile preamp allowing selection of input capacitance, input impedance and input gain to perfectly match whatever cartridge you have fitted. There are some examples of settings for 3 different Ortofon carts in the manual (included). I have used it with both moving coil and moving magnet cartridges and it performs perfectly. Needless to say it has a very accurate and detailed sound allowing your vinyl to sound superb. I bought it from new from Henley Audio 3 years ago and it has worked flawlessly. The case is very robust (made of metal) and is unmarked. Check photos for condition. Gold phono connectors and good quality earthing connector ensure reliable signal connection. The unit comes with its own power block and it is packed in its original packaging boxes. Please contact me if you require further information or photos. Thanks and happy bidding.

This Pro-Ject Debut Carbon DC Turntable comes in a gently used condition as I only used it a handful of times, it comes with the Pro-ject phonobox pre amp and all the cords needed to use both! The original felt mat was replaced with a thick leather one as it negates static electricity while still cushioning the record.

Pro-Ject Pre Box S2 Digital - Digitaler Mikro-Vorverstärker mit MQA und DSD512 Diese geniale kleine Kiste wird verkauft wegen Umstieg auf einen größeren Streamer/Vorverstärker. Sie wurde 2021 gekauft und ist technisch und optisch wie neu. Der Versand erfolgt in Originalverpackung mit allem Zubehör und Bedienerhandbuch. Das Gerät stammt aus einem tierfreien Nichtraucher-Haushalt. Aktueller Neupreis ab 315 € Die dazu passende Stream Box Ultra steht ebenfalls zum Verkauf! Hier noch die Infos: Eine ultra kompakte Performance-Revolution! Die Pre Box S2 Digital markiert eine neue Ära für die Komponenten unserer S-Serie. Zum ersten Mal verwenden wir einen Doppel-Mono Aufbau mit höchstklassigen D/A Wandlern von ESS Sabre. Deren Flaggschiff DAC-Chip garantiert höchsten Hörgenuss zu einem leistbaren Preis. Dieser DAC ist fähig, hochauflösende Dateien bis 32bit/768kHz PCM und DSD512 zu wandeln! Pre Box S2 Digital ist auch das erste unserer Produkte welches MQA Hardware Dekodierung unterstützt. Mit ihr kommt auch die Premiere für unseren proprietären Optimum Transient Filter und unserer proprietären Clock Schaltung. Digitale Audio ist die Kunst der Zeit, mit unserem proprietären Clock Design konnten wir Jitter-Werte von 100 Femtosekunden realisieren, Werte welche viele hoch angesehene und respektierte Clock Generatoren in den Schatten stellen! Mit organischen Propylen Kondensatoren und Thin Film miniMELF Widerständen konnten wir dieses kleine Wunder bauen welches auch viel größere und teurere Hardware deklassiert. Mit acht digitalen Filtern kann der Kunde den Klang nach seinen Wünschen formen. Die Pre Box S2 Digital ist voll fernsteuerbar und kann sogar die Wiedergabe-Software des Computers steuern.

This is an excellent sounding DAC. The exterior is in very good condition. As you may observe in one of the pictures, some pixels on the display are not displaying as brightly as others. Otherwise, I would probably describe this as near-mint condition. Pre Box S2 Digital Digital micro preamplifier with MQA and DSD512 support. A performance revolution in a small package! Pre Box S2 Digital marks a new era for our S-series components. For the very first time we are using a dual mono configuration with the highest class D/A converters of ESS Sabre. Their flagship DAC-chip ensures highest class audio in a small and affordable package. This DAC is capable of high resolution audio up to 32bit/768kHz PCM and DSD512! Pre Box S2 Digital is also the very first of our devices to support hardware MQA unfolding. It’s also the premiere of our proprietary Optimum transient digital filter and our proprietary clock circuitry design. Digital audio is the art of time, with our new proprietary clock design we have managed jitter rates of unrivalled 100 Femtoseconds, this easily outperforms many renowned and respected audiophile clock generators! MQA hardware decoding is only possible via the asynchronous USB input of Pre Box S2 Digital. With organic polymer capacitors and thin film miniMELF resistors we were able to create a tiny device that will blow away even much bigger components for a much higher price. With a total of eight digital filters the sound can be shaped precisely to the listeners liking. Pre Box S2 Digital is fully remoteable, it can also control the playback software of a computer. You can use Play, Pause, Forward and Rewind straight with your Pre Box S2 Digital!

Our precision Tube Box DS2 phono preamplifier benefits from outstanding circuitry design by the brilliant Czech engineer, Dr. Bohumil Sykora. Compatible with most MM & MC cartridges on the market, it offers two turntable inputs so enthusiasts can easily toggle between two different turntable/cartridge combos. Continuously adjustable (‘on-the-fly’) input impedance for low output MC cartridges is a must-have feature that allows you to ‘tune’ the loading to achieve the sonics that best suit your system and your ears. Other features include input capacitance for MM cartridges and a switchable subsonic filter to stave off mechanical noise. All components including the tube output stage and polypropylene capacitors are audiophile-grade and guarantee a breathtaking sonic experience.
