the biggest myth is that more power is better. MOST speakers in normal listening environments (not giant spaces) are happy with under 60 watts amps and will not benefit from the extra power.
Loudspeaker warranties and black market products
Perhaps loudspeakers represent one of the wildcard purchases on the used market regarding warranties. Some manufacturers offer transferrable warranties. Others do not. And the real wildcard in the used market are black market products. Such products often are not disclosed by the sellers in their listings. The buyers of black listed products have no warranty coverage and often encounter a refusal of service if issues should arise. So I’m curious what the A’gon community user experiences have been regarding warranties for their purchases of loudspeakers.
