The Rhumba Extreme 1.4 is our best value in a linestage tube preamplifier. Fully balanced connections, with sonics very near to our flagship Rhythm, for $8,500.

Changes in the 1.4 vs. the 1.3 model:

• The 1.4 has improved circuits in the power supply and gain stage
• Better stock tubes: now using American-made tubes from the early 1960s (still 12au7’s or equivalents)
• Higher-quality capacitors used in the regulator and filament sections of the power supply
• An all-brass bottom panel that provides more holographic and natural sound quality (and is heavier)
• Now with 2 fully balanced XLR inputs and 2 fully balanced XLR outputs (still has 3 RCA inputs and 2 RCA output pairs)
• new “Gaia” feet from IsoAcoustics, the feet found on our flagship Rhythm preamp
• an entirely new circuit board, with a design that improves grounding and channel separation
