Boulder – 2150 Mono Power Amplifier

The 2150 Mono Amplifier is the beneficiary of 30 years of amplifier design. It replaces the renowned 2050 Mono Amplifier, a benchmark product that stayed in continuous production for almost 18 years.
nHaving the perfect template to build on, we analyzed, improved, and evolved the 2150 into something much greater than its predecessor. It outperforms it in every way. After all, we don’t aspire to benchmarks. We outdo them.
