I bought this as my very first desktop amp. I wanted an item I would have reasons to keep for a while. The GT40 as many functions and that was my reason... I'm also thrilled to be able to listen to my moms old Sony turntable and her vinyl collection.
I can't compare it with any other headphone amplifier as I always used directly headphone jacks that were only 3.5 mm deep.
The GT40 was never reviewed seriously on head-fi but outside of it the "general consumer" websites (you can see tons of review links at the product page on furutech.com) it pretty much got 5 stars out of 5 everywhere.
I love having an amplified sound, I feel like it amplifies the goodness of an headphone as well as all of its flaws, and all in all more revealing of the thing you're listening to.
Before receiving my unit, right before Christmas actually, bought from an head-fier who had placed an ad here, I was scared that 90 dB SPL wouldn't be enough to clear all white noise during listening session. I found out it was not the case, even with sensitive IEMs. I need to almost double my usual volume to notice such noise between tracks, and in my case it's no big deal because this thing made me realize a lot of my favorite tracks already presented white noise, some of which I had never heard. So yeah it's more revealing and not noisy at all.
You're a lot younger than me but you might be even more experienced than me in audiophile listening and describing the sound of a particular set-up. I'll say that I feel pretty much the same way about my unit too (energetic and vivid), plus it's definitely audiophile sturdy and shielded, cubic, and with a machined metal volume knob.
I'm happy a recent topic appeared about the ADL GT40 (thank you
!), I hope some people will be able to further the topic and give out some more opinions. The Furutech Cruise was more talked about but not so much.
I believe people doesn't want to associate Furutech with more than plugs and cables.
So you live in Canada too? Did you asked for it? who in your family knew you'd like to receive such a present? I think it's great for you, or for any music lover because it's a definite improvement for computer audio.
Some Ontarian hi-fi stores (I seen at least two ads on Canuckaudiomart) gave away Furutech Formula 2 USB cables with it. One shop even gave a 100$ rebate along with the cable. You got that nice braided black and blue cable?
I find the GT40 to look great on the inside too! (

(which, for me, was an important factor for deciding to purchase... that's right, the way it looks inside! not counting the resistors and stuff or anything but more the overall look of it all)
