Thanks, same here buddy, i find your posts, informative, objective and respectful, wich, as you know, is not always a given here on Head-Fi, especially when we venture out of the Grado fan club shelter.
To be honest, i have thought about getting a more expensive amp. Some might say that the Little Dot +1 is not enough amp for the 1000 family, but ever since i've heard how awesome my SR80i's sound with the L-cush, straight from the headphone output of my vintage Marantz 2220B reciever, I'm not sure that investing a lot more, would net me, much better sound.
Amen...I love the fact that our little Grado thread here tends to stay so friendly and respectful. This is always the first thread I check whenever I log on here, and you're in a very small group of posters that I've been enjoying and trusting since I first signed up here in late 2011.
The amp I'm really curious about for Grados, especially since I have the GS1ks kickin' around here, would be the Mapletree amps. Dr P built my first tube preamp several years ago and it was just a great buying experience. I've been close a few times to sending him a few more bucks for one of his headamps, cause i've heard that they have amazing synergy with our beloved Grados. If I ever am lucky enough to own the PS1ks, I'd certainly get them a nicer amp just out of principle lol. But in the meantime the Little Dot is just incredibly satisfying.
