## Description

SMSL BLACK SAP-7 Portable Headphone Amplifier with USB Power Supply Port for Cell Phone PC MP3 This excellent portable headphone amplifier is specially designed for high impedance headphones when connecting with lower output power devices (cell phone PC MP3 etc)

Review: great sound quality - I bought this to go with my Schiit Modi 2. It works extremely well, great sound quality, very clear. I have used it to drive Takstar Hi 2050s (very underrated cans, which are awesome for the price) and Sennheiser HD 558s. Even with the 558s, it could go loud enough to (probably) cause hearing damage, so power is definitely not an issue. As this is a solid state amp, there is zero distortion and zero hiss, which is great for (relatively) low impedance cans, where hiss can be very pronounced. Also, the ability to switch between 3.5mm and RCA audio inputs is a pretty slick feature, although I don't use it that much. The volume pot is decent, but nothing to write home about. Pros: - excellent value for the price - very powerful - nice aesthetic design - low distortion/hiss - switch between two inputs - excellent build quality Cons: - blue power indicator behind the volume knob is slightly annoying in dark environments Overall: 10/10 - excellent value for the price, great build quality, would recommend for any low-medium range audio setup!
Review: Worked Once - I ordered this a couple of months ago to try with some power hungry headphones like Fostex T50 MkIII and and Beyerdynamic 990Pro. The day it arrived, I unboxed it and put it to the test. My headphones exploded (phonically). Never knew they could sound so fantastic, all because of this SMSL sApII. I put it in my file cabinet as we were going for an extended family visit. A couple of months went by before I pulled it out again... last night. Excited about finally using this thing, I loaded TIDAL, grabbed my Fostex, plugged in and nothing. The SMSL got really hot and I got no sound out of it. Today I have tried it again with nothing. I've used line in and audio in with the RCA plugs, nothing. My return eligibility expired two weeks ago, so although I've only used this amp once (and it worked fine), I have no option on desertcart for return. I buy a pile of stuff from desertcart and give great reviews on pertinent orders, especially within the audiophile community. I'm very disappointed that this SMSL amp only worked once and more disappointed that I have no recourse with the place I buy everything, desertcart.

### ⭐⭐⭐⭐ Dead Out of Box, then Resurrected
*by D***H on November 17, 2015*

One thing I'd like to point out first. There are currently at least four listings for this identical product on Amazon, each with its own set of reviews. Check all the listings for "SMSL sApII" if you want to get a real feeling for buyers' experiences. I don't know just how to do the stars on this. The problem is that, like two other reviewers, it was dead out of the box. It just click-click-clicked and no sound other than pops out of the output. Well, before I returned it, I did try it with a 20V laptop power supply I had lying around, and problem disappeared. It now (so far) works reliably, and actually sounds great. And, an update. The seller ("Global Cyber Mart") made me a small refund to apply toward a new 24v power supply, which arrived a couple of days ago. It works well, and even sounds marginally better than it did with the laptop supply. I bought a good 24v 3A supply from Binzet. Very happy with it now. I bought it to drive a couple of pairs of high-impedance phones I have, an old pair of AKG K240s (the old 600 ohm version) and Sennheiser HD580s (300 ohms nominal, but rises to almost 600 ohms at 100 Hz). Output sections of portable devices, even the Pono, just couldn't quite drive these. This drives them divinely. Away from the main system, I use the Pono line out, or a couple of old portable CD players with line-out, as sources. Everything sounds gorgeous, especially the Pono... There's plenty of detail to tell just how much better the Pono is than the CD players. So, I love it, so far, but not at all happy that the included power supply is evidently useless, nor particularly confident that it will continue to serve with this replacement power supply. I hope so, because it does exactly what I hoped it would do--drive a couple of 'phones that modern portable devices just don't have the output for. And, a further update 1 year + out. With the new power supply, everything is good. Have had no problem at all yet, and I have come to appreciate just how good this sounds. I was listening to the Sennies through the headphone output of my Onkyo TX-SR805 receiver over the holidays, and it just doesn't sound half as good as the SMSL. I've upped my stars from 2 to 4, as it was obviously the power supply which was supplied that was the problem. It seems this is quite a common problem. A decent 24v 3 amp dc power supply will do the trick. The amp is solidly built (it's taken a dive off the shelf more than once), all the switches and pots are holding up well, and I am very happy with the sound.
