samberger0357 Posted September 20, 2018 Report Share Posted September 20, 2018 I presently have 2 amps that I can use with my restored 3a's: A Harman Kardon Citation 22, which is 200 watts@4 ohms, and has a high currrent mode, and a Nikko Alpha 230, which is 130 watts@ 4ohm, and is current limited. Both amps are fully restored. My dilemma is that the preamp I'm using is a restored McIntosh C24. While it's output impedance is not to be found anywhere, according to literature one should use amps that show a minimum of 47-50K ohms with it. On another forum a graph was produced using the C24's schematic which indicated that McIntosh's recommendation was correct. The HK is 22K, and the Nikko is 50K. The HK produces more bass, almost to the point of bloat on some recordings, where it would seem the loudness setting is being used even if it's not. That said, it sounds very good overall. The Nikko produces less pronounced bass, and is a little drier, so it sounds more "accurate". So I'm looking for some guidance/thoughs as to the amp that folks here would suggest using. It would be nice to find a high current amp with a higher load, but that doesn't seem to be in the cards at the moment. Quote Link to comment Share on other sites More sharing options...
