I am testing my new SR-71A amp side-by-side with my old PA2V2 amp using the same source and Sennheiser HD-580 headphones.  I am really surprised to hear virtually no difference between the two amps.  Am I deaf?

i just purchased a emmeline SR 71 portable headphone amp and i am considering buying the NU force NE 700M  in earphones they retail for $75 anybody familiar with these any suggestions on what might sound better,most bang for  the dollar, cant spend big bucks right now. 

I have a SR71A while one thumb screw at the back got lost accidentally. I cannot find any replacement around. Could any one kindly tell me where & how can I get one in UK ?   I actually asked Ray but he said he is too busy so only posts with FedEX, which means a pair of thumb screws would...

I would like to run my Logitech Squeezebox Transporter directly into my Ray Samuels SR-71A amp, and out to my AKG 701 headphones. Will this kind of connection damage anything along the way?   Thanks

Help, please Head-Fi-ers!   Head-Fi came to my aid when I needed to dip a toe in the world of headphones - and the advice I got here was brilliant. I ended up with AD700s for awesome soundstage and detail, and Shure SRH750DJs for travel, bass and all-round brilliance. I am very happy.  ...

Hi, I have an opportunity to get the beyerdynamic a1 at the price of $630 or the SR71-B at MSRP. I have a pair of dt770/80 and dt880/32. Acoustic, ballads, piano, pop and rock seem to be the most common categories I listen to.   Which would be the better choice? Can the SR71-B drive the...

Guys, I need help! I hooked up my SR-71 to my iPad and to my disappointment it hasn't been a good experience. I receive a lot of background noise at high volumes. My headphones are Edition 8's and 990t. The 990t sounded the worst out of the two. By the way this only happens when watching iTune...

I have a pair of Sennheiser HD650 that I currently use with my Yamaha RX-V3800 and my Samsung TV (52LN750A.)   I'll be adding the AKG K702 to my collection very soon. I bought the K702 because of the reviews I read here. I'm hoping they sound better or are at least equal to the HD650.  ...

http://microshar.org/product_info.php?manufacturers_id=&products_id=117&osCsid=2 This amp much like its previouse version the 109+ it carries a lot of the same specs but it seems with a few tweeks. Now the 109+ drew breif attension with a headfier actually trying it out but has yet to be...

I was going to email Ray Samuels with this, then it occured to me that a post might be of more use.  I've had my SR71A for about 2 weeks now and have used it quite a bit.  My review of it is this.  Bravo!

Hi all, This is my first post. I currently own a MS-PRO which is used with the RSA SR-71A (portable). Using the benchmark dac1 pre as DAC. Prefer the sound with the SR-71A compared with the HPA2 headphone from benchmark. Warm and more pleasant. If I were to 'upgrade' from the SR-71A to a...

I see this amp available at CryoParts and ALO Audio, but no mention about it at all on Head-Fi. So...   ...Any owners?   ...And how does it compare with other 9V battery amps (RSA Hornet, RSA SR-71, iBasso D4, Graham Slee Voyager, etc)?

Hello all. I'm currently looking in to upgrading the amp in my computer/desktop rig (Mini m3 -> Ety ER4's) and have been reading a lot of reviews on Ray Samuels amps, in particular the SR-71 and Mustang. I then came across this review by Wes Phillips regarding the Channel Islands Audio VHP•1 ...

Hello everyone，I just found a 1100mah rechargeable 9v battery that made by Utralife Batteries. But I'm afraid of buying it because the common batteries that made by PowerEX is only 230mah/300mah. Would anyone tell me that if I use a 1100mah rechargeable battery, will it break my SR71A? Thank you...

Been doing a bit of searching to see what folks think of the sound of the Shadow and ALO Rx, specifically with the JH13. I have a pair of the JH13 in the works and was looking at getting a portable amp. I already have the SR-71A as my lone portable at the moment and plan to first evaluate the...

Hello, so like the title says I am looking for an ultra portable headphone AMP to use with Sennheiser IE8 and COWON D2. Size of COWON is: 78x55.4x16.6mm (WxHxD). Any recommendations would be very helpful Thanks

Hello, I currently use the RSA Hornet with the Ultimate Ears UE-11 and was thinking of getting the JH Audio JH16 or the UE-18 and possibly upgrading the amp if there has been any breakthroughs in portable amps that can offer me something that would be considered better than what I currently...

I'm new to the forum, and have recently purchased a R/S SR-71A Blackbird. It's a great amp, but I'm a bit lost about the three gain switches. Would someone be willing to give me a detailed breakdown of how to use these three settings, and why? Specifically, I will be using it with the...

Like many of you, for years now  i  have wondered which rsa would best suit my needs.   the fact is Rsa makes many fine products of which i have been fortunate enough to use the venerable Predator,    which has really come in handy the past 2 years, but ive always wanted to try another of their...

Is there a portable amp that is able to power AKG K701?

Hi guys,   I've been looking for some options to replace my recently sold Cantate.2( which I regret doing ). Initially, I was looking to get the Symphony.2, but it's way out of my wallet's league.   I started thinking about cheaper options to use at home, listening to CDs and lossless...

I am looking for an amp for an se530 and HD580/HD650. Budget is $500. Most seem to be recommending the sr-71A blackbird or p-15. I would like to know if there are any others that are known for being paired with them. ty for ur time and reply   "New guy"

with balanced input and output or single in and single out or single in and balanced out! It has a 26 plus voltage swing in balanced, 12 to 14 volts in single ended and plenty of power. The size is the same height as the Protector, a 1/2 shorter than the 71a and as wide. The measurements are...

I'm looking to get a new portable headphone amp and the P-51 seems perfect. I don't really wan't to spend anymore than $400 and RSA's new SR-71B seems like overkill based on what I'm looking for. For $400 are there any other recommendations. If I'm willing to DIY does the Mini^3 come close to...

Just wondering what you guys thought the best portable amp for these two earphones might be. As far as sound quality is concerned I prefer a more neutral sound but warm. The ortofons are my ideal but its obvious to me that the w3's are better at some things. I dont know if its possible but i'd...
