Description

Phono stages by  Lehmann

audio

  have been well known worldwide for many years. There have been numerous 

requests to finally develop a top-of-the-line phono stage following a cost no object design. 

Lehmann

audio

 is proud to present the new and improved Silver Cube phono stage to sophisticated listeners who 

really feel the longing for true sound reproduction of their vinyl records. With the Silver Cube audiophiles will get  
maximum space, air and soundstage depth and width, paired with stunningly fast attack response. Pace, timing,  
swing and dynamics of the Silver Cube will not leave anyone untouched. Owners of the Silver Cube phono stage will 
hear an open and natural sound with a full body.  

The Silver Cube is capable of drawing the listener into the music like only real music can do! What's more:

 is known to always aim at the highest goals at a real world budget.

Technical details:

AUDIO SECTION

- Special operational amplifiers for professional audio use to realize enough gain for even the lowest output cartridges 
available.
- Only Mundorf tin foil MKP caps in the passive RIAA filter network
- NEW: non magnetic resistors in the small signal path
- Discrete FET output stage without any negative feedback highly buffered with high grade electrolytic capacitors and MKPs 
- Strictly built dual mono audio layout
- Each gain stage has its own extremely fast parallel voltage regulators buffered with three different capacitors for each 
voltage
- Impedance load and capacitors adjustable from the rear side for practically any cartridge on the planet
- Gain up to 67dB in four steps also accessible from the rear side
- Additional choke filtering of supply voltages on the audio board
- Case milled out of one block of massive aluminium acts as a heatsink
- WBT audio connectors
- Neutrik Power supply connector with gold plated contacts
- NEW: WBT Nextgen RCA connectors
- NEW: SSC absorption feet underneath the unit

POWER SUPPLY

- 120W toroidal transformer with isolating coil between primary and secondary coil
- Chokes on the secondary side
- Additional filtering
- Separate set of ultra fast recovering diodes for each secondary coil
- Very low noise regulated voltages 
- Neutrik connector with gold plated contacts
- Shielded cable between power supply and audio section 
- Voltage selector 120V/240V
- NEW: SSC absorption feet underneath the unit
- NEW: AHP audiophile fuse supplied
