Great sound for such a small unit.
Amazon Customer
When volume control is turned all the way down I can still hear music and hissing from the speaker.
Bluetooth works great from my S3 phone and pairing was simple.

Unfortunately, this amp would be totally perfect for my needs, if it weren't for the fact that the sound quality is completely unacceptable. There is a constant background hiss (white noise) output to the speakers while audio is playing. After pausing or muting the sound, or during silent gaps in the audio, this hiss carries on for about half a second after the audio as gone quiet, and then abruptly cuts out. The fact that the hiss cuts out after a brief pause makes it even worse - if it were constant I think I would probably get used to it and filter the noise. But the fact that the hiss stops so abruptly draws attention to it. (I'm convinced this is related to the amp itself, because I have another amp in the house, with an external bluetooth receiver, which doesn't demonstrate the same problem.)

I suspect that if you only listen to music which has no quiet gaps, at medium to high volume, you may not notice. But if you want to listen to music quietly (eg at night time), or if your music has frequent quiet moments, it's basically unlistenable.

It's entirely possible that my unit is faulty. However, I see another review on here in which the user had this problem with his original unit, and two replacements. When I spoke to the supplier about the problem with my unit, they immediately offered a refund, but were not willing to replace my unit, which makes me suspect that they know that I'll be dissatisfied with any replacement that gets sent.

This is a crying shame because, if the output was acceptable, these amps would be excellent - form factor is great (everything else on the market is unnecessarily huge), they look good, and the controls are excellent. Sadly it's just not fit for it's main purpose - outputting audio.

Size Name: 100 Watts
Grace Digital is an exceptional company with superior customer service and return policy that rivals Amazon. I bought 2 units directly from the company, because the GDI-BTAR502's were out of stock on Amazon(where I, as a Prime member, prefer to order from) at the time. I also found a good online discount coupon and Grace Digital offered free shipping and 30 day "hassle free" returns.

The GDI-BTAR502 is a near excellent amplifier with a combination of features, specs and performance that are difficult to find in mini class "T" or "D" amps even at higher price points. Both with Bluetooth and direct wired setups the sound quality was rich and full with no distortion that I could notice even at moderately high volume levels. The front panel and remote control work well and are nearly full featured; the remote lacks the balance function and the front panel lacks a full mute.

Unfortunately, my first 2 units had a fixed low level white noise/audio hiss that I could not eliminate by any means except by pressing the remote mute ( or powering off ). At most listening distances the hiss would seem to be drowned out by turning the volume up just past the lowest one or two volume settings, although the hiss was still there if your ears were within a foot or so from the speaker.

Technical support was exceptionally responsive with troubleshooting. Even the head engineer/CEO got involved. I tried my own solutions. When nothing seemed to work or work well enough, Grace Digital sent me two new replacement units BEFORE I sent the first pair back. They also covered shipping costs.

Sadly, the second pair had the same issue for me, so we threw in the towel, and Grace Digital lived up to it's no hassle return /refund policy - even more so - in my opinion.

Size Name: 100 Watts
Length: 7:32 Mins
Grace Digital's GDI-BTAR502 100 Watt Digital Integrated Stereo Amplifier is a nice, compact bluetooth amplifier with flexibility in how it can be used. It is not as incredibly powerful as some people are characterizing it. It's 50w x 2 into 6 ohms. As a point of comparison, my self-powered speakers that I use for my Mobile DJ business, Electro Voice ELX112P, have a 1000 w Class D amplifier built into them... so a 50w class D amplifier is not all that. It is certainly adequate for its intended purpose of powering small bookshelf or floor standing speakers however..; not with earth shattering loudness but decent performance for its size.

Here is what is included:
-The GDI-BTAR502 amplifier
-48" 3.5mm, male to male aux cable
-AC power adapter (UL approved)
-60" AC power cord
-68" DC power cord
-IR remote control & battery
-External Bluetooth antenna
-1 year warranty

The amplifier is quite small measuring only 5 1/8" x 8" (from front of volume knob to back of bluetooth antenna) x 1 3/4" and it weighs just over a pound. Inside that tiny enclosure is a 40w RMS x 2 (into 8 ohms) Class D digital amplifier. This will easily power bookshelf and floor standing speakers and provide enough power to create some serious decibels.

-100 W class D digital amplifier (50w x 2 into 6 ohms)
-Bluetooth 4.0 and aptX (can remember 8 device pairings)
-100-240V, 50/60Hz, 25V 4.3 switching power supply
-Frequency Response: 20Hz-20kHz
-THD <0.1 @ 50w

On the back side is the antenna port, DC in, USB 5V 2A output, Aux in, Line out and L + R speaker binding posts. The USB port is only there to provide a means to charge or power a USB powered device.
