Ray Samuels Audio Mustang P-51

Posted

Pros: Fantastic sound from a tiny little amp

Cons: so small it's actually hard to couple to a PDP

I received a loaner of the new Mustang P-51 portable headphone amp from Ray Samuels Audio. The impossibly small Mustang is quite full featured – lithium Ion battery built in, 3 gain settings. Smaller even that the Tomahawk. Same styling as other RSA amps, which is to say a very attractive anodized metal case. The Mustang, according to Ray, can deliver more than 2 times the amount of current that a Tomahawk can. Pretty impressive. Headphones used for this review were the Audio Technica AT-ESW9, Kenwood K1000, and the Sennheiser PXC-350.   Build Quality: A+: Attractive metal case, properly sized metal knob, very sturdy connectors. Doesn’t get any better.   Treble: A: Amazingly...

The Mustang of Portable Amps

Posted

Pros: Clear and Liquid sound, fabulous mids, small and portable, insane battery life

Cons: Expensive, No USB Charging

This is one of those times when you just have to have the most expensive toy on the block.   The P51 Mustang is one of those products that sit in the high end luxury category of its product range.

Great headphone amp! Cost benefit ratio "good".....

Posted

Pros: Outstanding Build Quality, sumptuous mids, tight lows and extended highs

Cons: It's not an SR-71b or Shadow. Not really a con, but output matters.....

I bought this headphone amp after having met Ray Samuels at a Headphone show.  He made it absolutely clear how much he valued over-engineering his pieces and how much he prioritized long term reliability.  I've bought other Headphone amps since (A  FiiO E17 which is also a DAC).  It offers really stiff competition and it's probably better value for the money.  But I'm not sure if it will hold up like this P-51 has. (I will say, no complaints thus far.)  The E-17 charge lasts about fifteen hours and I've never been able to actually run this Samuels Headphone amp down.  It just goes and goes.......but I will say that the E17 is a little more muscular in...
