Backart Labs Rhumba Extreme version 1.4 Linestage Tubed Preamplifier
Looking to upgrade from my current solid state linestage. Many users have recommended the Backart Labs tubed linestage Extreme version. Does anybody currently own this product or have heard this product? The retail price is $8500.00. Would appreciate any comments that could help me make a purchasing decision. Thank you.
