Well I'll give this a quick shot. I'm not amazing at reviews, and haven't done many so try to graze over some awful mistakes :-)
Alright well here's my setups.
Asus D2X>Toslink>DAC_I>little dot Mkiii
My mkiii uses blue glass ef91, upgraded power tubes as well.
Asus D2X>Toslink>DAC_I>little dot Mkv
HD650 (Clou Red Cable), k702 (zombie x cable!), Grado sr225, beyer dt880
Initial Impressions: Wow, this is a pretty stand-up amp. Forgot how powerful it was too.Listening to Coldplay's 42
I picked this song because my girlfriend is a avid coldplay fan. One day she decided to give my set-up another listen, after not understanding anything of the headphones I was trying to show her. She said "it's strange its almost as if the singer is right infront of me and the piano is far off to the left" My heart fluttered
I'm struck by how detailed vocals are, especially since this is a tube amp. Saliva can definitely be heard. Unfortunately, later in the song when the rock picks up, I have a sense that the music backed off. Strings obviously turn out fantastically, and very detailed.
Pros: Very strong presentation of strings, very very detailed, considering it is a tube amp. Very bright and peppy, matches the hd650's pretty well. Bass is surprisingly deep and transparent.
Cons: Unfortunately I have to compare it to my audiotailor jade, which is a slightly more pricey amp. Strings are not as life-like as they are in the jade (However the Jade isn't as detailed). Soundstage was pretty narrow as well.
Obviously a very powerful amp that matches well with HD650s. Provides a very neutral and flat presentation in comparison.
Pros: So detailed, every gasp of air is felt, and the saliva can be heard at some parts. Much more upbeat presentation when rock started. More upfront music
Cons: Strings are there, and can be heard, but there's not as much beauty or naturalness to them. Soundstage is really small.Listening to Peter White's by candlelight (Flac)
This song is a purely composed of 1 acoustic guitar. Soundstage is presented better, but still not as wide. Detail is still so remarkable, especially for a tube amp. Everything fades just naturally, without an echo or trapped feeling. This is actually a great song to match it with.
pros: Detailed guitar presentation. Everytime the pick hits the guitar string it's heard. Great presentation of strings
Cons: Still not too tubey for my liking. Soundtage is still not too wide.
Pretty decent representation. Still a fairly lifelike touch to the guitar
Pros: Very detailed, and good representation
Cons: Soundstage? What's that?
Sorry, I got a busy day so this is all I can do right now. If you have any other combos you'd like to hear I'll give it a shot (Different music, headphones, etc.). And I'd love to answer questions. If anyone is interested, I may be willing to sell this MKIII so I can look at a new portable rig. Thanks
