I saw your online review of the iCan before finally pulling the trigger on it. I wanted a smaller form factor amp that could stack on my Benchmark DAC and media player. Now that I've lived with it, I do like how powerful it is with a lot of options. I'm wondering if you noticed a difference with balanced vs SE headphone output? When it comes to micro-detail, I did notice that if I have everything off and it set to SS, and outputing SE, the amp then sounds the same as my Benchmark's headphone amp (which I find to be extremely flat). I also read about some other NOS tubes for it. I've gone ahead and put some Western Electrics in and it does add some more extension (wouldn't say detail the way I've found with tube rolling NOS tubes with my larger sized amp). The main problem with the amp is there's too many options for an indecisive person like me But I do find running my LCD-2fs in balanced, running tube mode, 10 X-Bass, and 0 3-D are my usual settings for most music. Only a few times have I found 3-D actually adds some neat effects, and more times have found it cuts down some on impact (wonder if it could also be more effective as a pre-amp). I've also found that if I want detail-centric vocals or guitars, I've got a collection of headphones now (Mr Speakers being a good compliment to Audeze for some acoustic music, and Focals for some trance). Keep your Youtube reviews going! I do find yours to be the best balance of length, overview, and fair opinions.
