First off, let me thank Boris for allowing me a chance to hear this great "little" integrated tube amp. It has received some very positive reviews from Positive Feedback and Affordable Audio and after spending time with it, I totally get why.
I have been using the i84 to drive Omega Revolutions (single driver Visaton B200 drivers) and the source has been a Bolder Cable modified (full analog mods + Gold Bybees) SB2 with a Bolder Cable modified Elpac PS. For most of my listening over the last few weeks, I have also added a stock Burson Buffer into the mix.
Here are a couple of quick pics (sorry it doesn't show all the gear I mentioned above):
All of my listening has been done with the stock tubes and a VH Audio Flavor 4 with a Furutech Rhodium power cord.
If I had to use one word to sum up my experience with this amp it would be "enjoyable". Maybe because I have lower expectations (sorry Boris and Louis) of this system than my main system, but I just found myself not thinking about what I was hearing, but rather just sitting in my chair and listening to the tunes. It didn't matter if I was playing jazz, rock, acoustic, male/female vocals, it all sounded good.
Now of course 15 watts with a single driver speaker aren't going to hit you in chest with bass and dynamics, but this combo never sounded thin or harsh. It also never sounded overly warm and rounded. I felt it had good extensions at the extremes and was well balanced. Of course the magic was in the midrange. Here there was a clarity and cohesiveness that is tough to find in multi-driver systems. The i84 mated quite well with the Revolutions and instruments such as an acoustic guitar, banjo, and percussive instruments sounded incredibly rich, textured, and lifelike. One of my favorite cd's to highlight this is Uncle Tupelo's "March 16-20, 1992" remastered cd. Whether it was the haunting "Black Eye", the sobering "Moonshiner", or the instrumental "Sandusky", I found myself getting pulled into the songs, closing my eyes, and feeling like the guys were just playing a few feet in front of me.
I need to run right now, but I will come back to talk more about this little gem of an amp.
