When I receive a review component, I start with no tweaks and plunk it beside the component it is replacing. Trying for a tabula rasa, I just plug it in and listen like a cello string, what resonates, what does the component bring, what insight does it provide? Does it excite me or am I... Read More »

"I've got a big one for ya." So said the UPS guy the day this bruiser of an integrated amp showed up. Not too long ago, it would've been considered "full-featured," and heaven knows it's certainly full-figured. Pictures don't quite do it justice. For anyone used to Naim or Rega or Arcam or the like,... Read More »

I have had a tube integrated amplifier from China on my desktop for several years. It cost me about $180. It sounds pretty good through my ancient and tiny Acoustic Energy Aego satellites. It's been a reliable system. It has some of the sweetness of tubes though it doesn't actually deliver tube loveliness. In a blind... Read More »

As far back as I can remember, I have been wanting to listen to a Vincent Audio amp. My curiosity with tube Hybrid solid-state amps being the first reason. They say if you think about something long enough, you create what you are thinking about. The Vincent Audio SV-737 came to my door a few... Read More »

This has been one of the hardest reviews I have ever done because the Michi X3 integrated amplifier really surprised me. Out of the box and into my system it performed so well that I was at a loss for words. Not so much as in spectacular audiophile terms, but because it just went straight... Read More »

The following review has been submitted by guest reviewer, Miguel Barrio. Boazu vs Ongaku: David or Goliath? Ever since I was a kid I have been fascinated by machines.

I can't remember the exact date, around the late eighties, nor the exact model, but I used to own a Rotel integrated amp in my fledgling days of High-End audio. It served me well. Admittedly, back then my audio concerns were mostly of function over form. Did it have enough inputs? Does it have a... Read More »
