Things have been going along nicely with the iCAN and the ODAC for the past few months.
I have been using two devices: the ODAC for the hp-amp, and the old Audiofire2 for the speakers. I wanted to cut this back to one, and have easier switching between the two. I also have a maybe plan of new proper active speakers to replace the M-Audio AV40s, and would need a central volume control to control two such speakers. So I had the idea of finding some sort of passive control.
I also had the idea of not buying actives, but buying passives and using an integrated amp that I have spare. I still have no idea which idea will win out in the end. It will probably be settled by some
impulse speaker buy! (Like the Harbeths currently on sale, if I had a lakh, which I don't) but...
I got fascinated by the McCormack Line Drive TLC-1
for sale on this forum. I even exchanged some I'm-not-buying-but-interested PMs with RoC about the box.
I had almost become convinced that the integrated amp and passives were the way to go.. I have a spare, good, amp sitting unused. Then came a price drop on the TLC-1, and I found myslef hitting the PM button.
There is a
rave review from John Atkinson in Stereophile. Looks like I'm now an "A-List" audiophile! :lol:
I had assumed that nothing could be better than direct connection ODAC --> iCAN. I had assumed that the pre-amp control functions might come at the cost of some sound quality, and that the best I could hope for would be transparency.
I was wrong.
I found that the
tape-out which, for ease of switching, I had hoped to use for hp-amp did, indeed, cost me a liitle, but after a short session of A/B/C testing of the three possible outputs settled down to listen to the
buffered output vi iCAN.
This was a somewhat unscientific test, which I could put into words as "which output makes me feel
least like going on to test the next one."
Listening to my current regular favourites, Mahler, Beethoven, Quicksilver Messenger Service, I might have posted about the experience here then, except that
I forgot about the internet!
I wonder if this might have happened if I had invested in some much higher-end phones amp like the Lehman. I don't know (yet

).
There is a new dimension in my headphones. Seriously, as the image is much more 3D. There is much better detail. A trumpet note does not sound the same from start to finish; the strings sound mass which is the bedrock of an orchestra's sound sounds less
like a mass; Kettle drum
thumps sound less like a thud, with more palpable decay.
I think TLV stands for
Transparent Line Control --- but I feel it to mean
Tender Loving Care!
I have always felt that my AT-ADH900s were capable of more with better amplification. They may not be perfect, they may (as reviewed) be a little bass-shy (probably just right with the iCAN's Xbass), but I find that, all over again, I
love them!
Of course, I can't help wondering how much better the Audeze would be. But five times the weight, for starters.
