Ken, I've had the amp for a few days now and I am extremely impressed! I've posted my initial impressions here.

I'm really not trying to be difficult, this amp is VERY intriguing, but Ken's statement quoted above is confusing to me. Can I infer the Rx is as good as the SR-71a, or is it "better?" In other words, if I already own an SR-71a, would I be upgrading if I get the Rx?

I'm very tempted to order this amp, would love to hear how it stacks up against, say the Lisa III.

proteuskim on another thread said the Rx "rivals" the Lisa III:

The sound quality rivals the Lisa III although i think the Lisa still has more power. portability wise, the ALO Rx wins. Only amps i had to compare it with were the Lisa III and RSA Hornet M. I will never touch the Hornet M again.

I do not want to be confusing here or misleading. Ray Samuels is a amp making wizard. His products are the absolute most refined portables, both in sound and physical finish. As a consumer and user of audiophile products like everyone else here I am grateful that Ray has so much stuff for us all to enjoy, the headphone world is super lucky to have his talent in the mix.

Matt and I are very proud and happy with the Rx but do not want to come off as arrogant in anyway. Ray is a portable amp making legend.

Ken, thanks again! You know, it ain't braggin' if you can back it up!

Here's the thing, while I thought the SR71 was a very nice amp, to me (using UE11's and an iMod) I thought the SR71 was bettered by both the iQube and the Lisa III. The Lisa III was/is a LOT better, my opinion. (I also like the P-51 at least as much, maybe more.) So, I guess what I'd love to hear is that the Rx is *better* than the SR-71a, not bragging, just reporting the facts!

Well if Ken is doesn't want to say I will, the Rx is a breakthrough product and to my ears it takes the portable amp market to a new level. I've owned and LOVED both the Pico and SR71 (the original and my favorite RSA amp) and think they represent the best of what the portable amp world has to offer.

The Rx takes the former best in class sound quality of these amps and raises the bar in my opinion

here are some of my thoughts from a review I just completed

I've had a little time with my new Rx now. 240gb 5.5 iMod, piccolino Black Gate LOD, Rx, JH 13s. I don't have a lot of experience with portable amps, but this sounds way better, immediately, than my iQube (which I really liked). Far more spacious, better instrument separation, better detail, faster, and especially tighter and more tonal bass. I never thought the iQube was veiled, but now I can tell that it is, slightly. I love how the Rx sounds.

It's a very nice object, too. It's not perfect - the endplate with the controls is slightly off-center on mine - but overall it's really nicely built. It's very thin and slightly larger in plan than my iPod; they fit very well together.

Great job, Ken.

John,

Thank you so much for taking a listen, again Matt and I are really stoked over everyone's reaction and kind words.

We're still getting many questions asking if the Rx amp can drive a particular set of Cans/IEMs/etc, so I posted this video on YouTube of an Rx driving two 4 Ohm 12" subwoofers.

I'd say it's pretty safe to assume that if the Rx can pound Metallica's Black album on two 12" subwoofers for over 18 hours without needing a recharge, it can pretty much handle any 'phone we throw at it (especially low impedance and multi-way designs).

Hey Sachu
