Integrated Amps


I'm debating whether to upgrade my Marantz integrated with a better performing and higher powered integrated or simply add a separate amp and use the Marantz as a pre-amp. I've looked at stepping up to the Marantz model 30 or 40n, PS Audio Stellar Strata, Music Fidelity M5si/M6si. But then the Heaven 11 Billie caught my eye.

Has anyone had any experience with the Heaven 11 Billie integrated amp? It's a hybrid class D amp w/ a tubed pre-amp. The reviews I've watched seem to give the unit high marks for sound quality, presentation, sound stage, and because of the tubed pre-amp, an analog warmth to the otherwise "cold" sound of a class D amp.

Another two cents:  Of all the amps the OP mentioned, the only one I've ever spent any serious seat-time with (i.e.  approximately 2 hours) when I was auditioning for a two-channel system speaker upgrade several years ago was the MF m6si.  That is one fantastic amp, provided it is matched to the right speakers.  I listened to it with a couple models of Paradigm towers.  Forget the model numbers but they were in the 3K and 4K price points.

I went from a Marantz PM8005 to a McIntosh MA352. A big change in budget, but the 200w hybrid integrated really paired well with my Dynaudios.  Since upgrading I'm not wanting for power, bass, details and soundstage. The MA352 does have dual subwoofer outputs if you want to add 2 SWs, but I found the speakers alone delivered all the musical bass needed in a 2 channel system.

I went from my Marantz PM-15S2 to a Technics SU-G700M2 and couldn't be happier. Improvements all around. Here's a link to a video review by The Absolute Sound.
