Michael Wechsberg has posted a review of the Backert Labs Rhumba 1.1 linestage ($2995) at Positive Feedback. His conclusions:
“Now properly equipped with an improved power cord, and sitting on top of the Townshend vibration isolation base the Rhumba became an even more wonderful performer that gave me many thrilling moments during several weeks of auditioning. It never took more than five or ten minutes to warm up and come up to full performance level, and that level was very high. ”
