PM-1s are very low efficiency mini-monitors with only 84dB sensitivity. The RA 1570 has 120 wpc...enough for a small room at medium volume with no clipping....but if you get carried away and overdrive tha amp you can damage the tweeter or crossover resistor. I don't believe there are any fuses or protective circuits, and the network is said to be a simple LCR with top quality components. If the level is way down I'd suspect that resistor.
Veiled 'wet blanket' sound from tweeters
Is it my speakers or my amp?
My gear consists of B&W PM1 with Rotel Integrated RA-1570.
I'm experiencing a lack of detail and separation from the speakers , specifically at the tweeter source. Switching between headphones (Grado RS1) and speakers, it is like there is a heavy blanket covering the tweeters. Midrange/bass is fine.
Switching sources between DAC/Turntable yeilds no difference.
I'm actually wondering if the crossovers have been damaged.
I don't really have the luxury of switching components. Any ideas on what my next steps should be?
