The converse is also true. Many have realized the beauty of high efficiency speakers and low power amps like DHT.
Why has amplifier power become a big issue
Back in the day I drove my Advent speakers that were very inefficient with 30 watts per channel. Today I run Vandersteen 2 ce speakers which are more efficient then the old Advents with 50 watts per channel and way more current. By most this is underpowering the Vandersteens, what has changed?
