Project Tube Box DS Valve Phono Stage

Price: £399.00


The ProJect Tube Box DS offers similar characteristics as the Tube Box S/E, but it also takes the sound performance and the feature-set to a whole other level when compared with its forebear.

Additional adaptation possibilities, including Pro-Ject's unique variable impedance dial and a switchable subsonic filter, make this new model ideal for use with high quality MM and MC cartridges. The high-quality valve output stage matches perfectly with these adjustment settings to produce a sound which far outweighs the product's attractive price point.

Key Features:

  • MM/MC switches on rear panel 
  • Unique continuously variable input impedance loading 
  • Switchable gain settings for MM and MC cartridges 
  • Capacitance switch for MM cartridges 
  • Switchable subsonic filter 
  • Dual-mono tube triode architeture 
  • Premium ECC-83 Golden Pin Tubes 
  • Ultra low-noise semiconductors 
  • SMD technology
