http://hem.passagen.se/erix15/skit/tekspectitan500.htm They are Swedish,but i think you can figure out main points of them. First comes to mind that 1% THD distortion at 1kHz,because if look some other receivers they are exp. like 0.06%THD at whole 20HZ-20Khz. Then i watched Pioneer´s VSX-D812-K specs and they look almost as "bad" as these what i asking for? Stereo (DIN) 2 x 100 W (8 Ohm, 1% THD, 1 kHz)(I put only Stereo here) http://www.pioneer.co.uk/uk/product_detail.jsp?product_id=3770&taxonomy_id=62-98 And what about Frequency Response: LINE that is LINE: 10 Hz 70 kHz, +1/-3dB Usually this is like 5 - 100.000 Hz, +0 / -3 dB I´m little bit newbie for AV things,but I´ll be grateful if someone can clarify these spec things for me?
