Pro-Ject Tube Box DS Phono Preamplifier (Black) (Mint - 2020)

Pro-Ject Tube Box DS phono preamplifier (Original DS model from 2020 production year. This is NOT the the most recent model - Tube Box DS2).

This, however, an absolute gem of a phono pre-amp, and sings like a bird! Truly brings your vinyl (really any genre takes a shine to the tube sound).

It pains me to list it.... but due to life circumstances, selling this mint condition gem for financial reasons, and this is priced accordingly (This beauty runs $999 retail and is worth every penny).

Includes OEM power supply, the preamplifier unit, power cable (with country adapters) factory accesories (jumpers for MC cart adjustment etc). and factory original box (w/ precision cut foam lining for protecting those valuable, fragile tubes! Will ship double boxed to ensure safe arrival) and once boxed is as if purchased "demo" (if not better!)

To top it all off - ships FAST and FREE via Reverb safe shipping w/ signature required - anywhere in the USA!

Pre-amp was purchsaed brand new in 2020, has ben used in a clean home audio setup for - sadly barely enough hours to break it in...! The preamp unit (and all parts/ components/accesories) are therefore in flawless cosmetic and functional condition. Safe to assume TONS of hours of playtime left in these beautiful tubes (which can be freely changed out with any tubes, if you have a different preference)! The included tubes are again at only ~30hrs playtime and unlikely to need replacement or repair anytime soon even with heavy play! (The unit also has an on/off switch with an LED indicator, so though I'll confess to being a bit forgetful.... the unit was never left on for extended periods of time and these tubes have thus never been overheated or otherwise abused! You can buy with confidence here!)

If i didn't mention it, the sound quality on this preamp is - staggeringly good. Seriously. With any MM cart - but especially a dialed in MC cartridge! (the front panel dial provides awesome options to precisely dial this in to work perfectly paired with your MC cartridge. (**all jumper pins // OEM instruction manual for re-calibrating to match the specs for any MC cartridge are included, so hassle free at that!!). That said - i ran this on an MM and loved it - and with any cartridge, experienced warm, clear, and that one of a kind “tube“ color.

Always happy to answer any questions and thanks for looking!

See below for more information on the Tube Box DS Specs from the manufacturer:

• dual-mono design using two dual-triode ECC83 (12AX7A) vacuum tubes for optimal channel separation
• compatible with moving magnet and moving coil phono cartridges

• adjustable input capacitance and gain settings for more accurate cartridge matching
• audiophile-grade polypropylene capacitors
• switchable subsonic filter to reduce low-frequency rumble and wasted amplifier power (-18dB/octave at 20 Hz)
• all-metal chassis for improved shielding from vibration and electromagnetic interference
• external power supply for reduced noise and interference
• gold-plated RCA connectors for corrosion-free signal transfer
• capacitance settings: 47pF, 147pF, 267pF, and 367pF (for MM and high-output MC cartridges)
