matgir99what do you define as a high-impedance device? No where in the description is this stated. please provide your source of this information. Only mention of impedence I can see is the output power for very high-impendence of 600ohms? "Output power: -114 dB THD+N, 2 Vrms into 600 ohms" which is confusing since mw output is stated for 32ohms...not that much power @32ohms either. thx
