Beat75: 75ohm SPDIF Cable with 75ohm RCA type Plugs 75 ohm cable for digital connections.
75 ohm is the standard both for cables and connectors. Anything less causes reflections and degrades digital signal. Optimum length to minimize reflections is 30cm (~12") OR 5 Meters
* Solderless connections further reduces reflections
* 75 ohm SPDIF cable from Gotham Switzerland (as used in some mega$ cables)
* 75 ohm RCA type plugs
You are not hearing what you DAC can do unless you connect with 75 ohm cable and plugs
Sorry this can not be DIY due to the special tool and die needed to achieve the solderless connections

Fusion Power Multiplier Modules
Fusion Module Outline and Specification:
Operates in parallel with the tube amplifier. Leaves the sound characteristics of the Tube amplifier intact. Allows the power from almost any tube amplifier to be multiplied
Can deliver up to 65 Watt into 4 Ohm for a single fusion module
Using four fusion modules can deliver up to 260 Watt into 4 Ohm

Technical Data for single fusion module:
Output Power (<2% THD): 40W into 8 Ohm; 65W into 4 Ohm
Distortion at 1W/8Ohm: < 0.3%
Power Supply Voltage: +/-35V @ 1.5A
Full Power Bandwidth: 20Hz – 80KHz (fusion module only)
*) The tube amplifier should be able to provide at least 16V RMS without clipping when not loaded by a speaker. Normally this is possible from the 16 Ohm Tap for 2A3 and 300B SE Amplifiers and for many tube circuits designed to drive headphones.
(**) for 260W into 4 Ohm the Tube Amplifier needs to have a balanced output with at least 32V RMS without clipping when not loaded by a speaker.
