If you have not experienced a dome mid range then be prepared for a surprise. These can go very loud without mid range compression. Effortless sounding and very articulate. Definitely worth auditioning. Telarc (Cleveland USA) bought some PMC's a few years ago which tells you a lot about the sound quality. ATC is worth a listen too as the PMC designs are very similar to ATC (apart from the transmission design which gives a quite different ultra-LF response)
