I have the Compact 7s and P3ESR and have also owned the Super HL5+. They sound nice with Line Magnetic and Sugden gear. I'm using a Simaudio 600i with the P3ESR. I think the Compact 7s are the goldilocks speakers in the Harbeth lineup. They are likely to convey the characteristics of whatever you power them with, whether that's the sound of tubes, class A , etc.
Marantz 30 for Harbeth Compact 7 ES 3
I’m considering replacing my vintage gear with a new integrated amplifier. I’d grateful for input on the Marantz 30. My speakers are Harbeth Compact 7 ES 3 with a REL s/812 subwoofer and my source is Innuous Pulse. I mainly listen to jazz, rock and acoustics. I’m also considering a Luxman 505z as there is a dealer near me. But I think the Luxman would be overkill. Any input would be much appreciated. Thanks.
