Well made.   But a yawnfest from beginning to end.   And Liam Neeson is barely in it.

Is there any specific usb dac/amp that is recommended for high impedance earbuds?

So what do you Grado fans think about Tyll Hertsens opinion on Grado?   From Innerfidelity:   Grado Back in the '90s, Grado was considered a high-end headphone company. Heck, it was just Grado and Stax back then. Time marched on, other headphone makers continued to improve their products...

Too bad the prices on SRS-2170 have increased so much since the release of the SRS-3100 :(

Yep, and they also release "limited editions" 

I used to own a Ming-Da MC-66 amplifier, and it was the most bass-heavy amp that i've tried on the Grado 325i, if that´s what you want.

Grado´s comfort is not an issue, unless you're going to listen for several hours without a break

isn't there something called damping factor, that is important to give the headphones the right amount of power?

Is there anything to compare the SR-002 to? or is it one of  kind?

Ok, I got an offer for 370$ on some buttoned RS2 without box, which is to much. I don´t know how old they are, but the seller tries to justify the price by comparing them to the RS2e.   Maybe i buy them if i could get a good price. Is there any way to tell how old the headphones are other than...

Are Grado RS1/2 with buttons rare? 

Hush (2016)     4/10   Not a movie worth watching. They spent some money in the production, everything else is mediocre.   Watch "Creep" from 2014 instead, that was awesome
