The 2270 was the most popular of the well respected Marantz 22xx series of receivers from the 1970's, but it was also a bit of an anomaly. It had the characteristic warm, beefy sound of other Marantz receivers; but it operated a bit strangely with 4 ohm loads. The 2270 was rated at 70 wpc at 8 ohms; but was measured at only 46 wpc at 4 ohms ... the opposite of what you would expect. So, you would need to exercise some care with speaker matching.
The tuner section was pretty top notch, if that helps any. I use two vintage Marantz receivers (2216B & 2240) in my various set-ups. The sound of the 2240 comes closest to the sound of the 2270. The sound has good rhythm and pace to it, but it is not as detailed or refined as some other amps that I own (NAD 320BEE; Musical Fidelity A300).
Associated gear: Speakers: Acoustic Research 302; NAD SB2. CD players: Musical Fidelity CD PRE 24; SONY SCD 555 ES; Music Hall MMF CD 25. DVD players: SONY DV560; JVC SA602
