Portable AMP for Grado RS1i

You're right that they're not hard to drive, but Grados do like a lot of current. 

I've had good luck with Ray Samuel's amps with my RS-1's.  They often tend to be slightly warmer/darker which is a nice compliment to the brightish highs of an RS-1.  My favorite combination was always the original SR71, but of currently available amps the Mustang/Shadow or SR71a would be a reasoanble alternative.  The SR71b is also great if you wish to try balanced and would like to go broke at the same time.

I've also spent time with several other brands of portables, but I always felt the RS stuff did the best job with that headphone.

Congrats on your purchase.

I've driven all sorts of Grados with the iBasso D2+ Boa, including the HF2, and it was a pretty good match.

Is the SR71b a new revision of the SR71?

Yes and no.  They share the SR71 name...but the SR71b is a different animal in that it is primarily a balanced amp.

Unless you are prepared to undergo the expense of having your Grados balanced AND you have a balanced source/DAC, I believe that the consensus was that there are better single-ended choices than the 71B - happy to hear otherwise.

At $650 plus postage, you are in striking distance of very good tube amps from the likes of Woo, Darkvoice and Little Dot - that may not be a fair comparison for someone whose needs are strictly transportable, but I feel that it needs to be said.  On the plus side, you wont spend your nights trawling EBay for tube upgrades.

I am very happy with the iBasso D12 and my RS2i headphones. I have a little dot 1+ on my desk that does wonders when paired with the D12 acting as a standalone DAC and when I want to head out to the backyard all I have to do is unplug the D12 and throw it in my bag. The combination is great and largely because the D12 is a great little DAC as well as a portable amp.

i listen to mine with a meier stepdance and am very happy with that combination

I used it on the SR-71 and thought is sounds great. Then I change to the Stepdance and it sounds even better. I am going to try on the Musical Fidelity X-Can V3 with dedicated PSU soon. I have the GRADO big earpad for the GS1000. Hope it will go well the the X-Cans,

This has been my best experience with portables. The Pico is nice as well.
