I am looking for help selecting a receiver for listening to CDs through headphones. I have tried researching this online and, as usually happens, the more I learn the more confused I get (impedance, RMS, SPL per milliwatt vs. volt, Ohm's law, etc.). I don’t use speakers. I have an Onkyo C7030 CD player and Sennheiser HD 598 headphones (impedance is 50Ω and SPL is 112 dB). I was using a big old 2002 Denon 5.1 receiver until it went bad. I then dugout my old Kenwood KR-A5080 receiver from 1996 until I could get a new one. The problem is I mostly listen to film scores, which are typically mastered at a lower volume than, say, rock music. When I listen to certain CDs, the loud parts can be distorted as if it simply can’t handle the full depth of the sound. I am assuming, perhaps wrongly, that my old Kenwood is the weak link. I doubt I spent much on it, but the specs are better than I expected: 100 WPC into 8Ω Frequency: 20Hz to 20kHz THD: 0.03% S/N: 75dB (MM), 93dB (line) I'm hoping someone can recommend a good but not outrageously priced model that will work well with my headphones, or at least suggest what specs I should look for in terms of compatibility. Or I should get a headphone amp? Any advice would be appreciated. Thanks.
