[0.46 lb] I was suprised how this small DAC/AMP beautifully sounded.
Worth every penny.

[Single Channel] Inexpensive, very light weight, folds flat, and works great with the Center Point Stereo Spacestation. Much better than alternatives I've tried.

[0.46 lb] The Fisher was 5x the price of every other product in this category, so I was skeptical. I connected to my Westone Audio custom in-ear monitors, and OMG, what a difference. I had been driving them with the headphone amp in a small Behringer mixer. The difference was striking! More definition, more detail, like the fog had lifted. I don't know what sort of black magic this is, but the way this amp pairs with the drivers in my IEMs is nothing short of stunning.

[2x AAA] The Go blu is great for portable use. It matches well with my
LETSHUOER S12 Pro IEMs. It has a livelier sound than DAPs I've used. I use my Pixel 7 running Plexamp. I connect using LDAC to the Go Blu. Then I use a Balanced connection from the Go blu to my IEMs. I've experienced no Noise/hiss using the balanced connection. If you're concerned about the no clip issue B&H sells iFi's Go blu leather case with the integrated clip. I've also tried the Go blu with easy to drive headphones and it did fine. I haven't tested the bluetooth distance, but with the phone near me I never loose conections. I have rarely noticed a skip but since I'm streaming music from my NAS to Plexamp on my phone, then using bluetooth to the unit, who's to know what causes that. It might even be the files. Overall, I'm very impressed with the Go blu. It turns almost any headphone into a bluetooth headphone.

[2x AAA] I've been driving my Westone IEMs with a little two-channel Berringer mixer. Connected the Fisher and, OMG, it was like the fog had lifted. I was skeptical. This thing was 5x the price of several other monitor amps I had looked at. But I bought it anyway on the recommendation of a sound engineer. Worth every penny.

[0.46 lb] I bought this for providing audio during film shoots. The design seems really tough, all metal construction. Looks like something that could be dropped on the floor a few times and still keep working. Good clean amps, but not a huge amount of gain. A few very minor critiques: uses AAA batteries ( I would have preferred AA as everything else on set uses AA), case is easy to open with ballpoint pin but can be put on backwards and then does not quite lock when closed (either make it impossible to put on backwards or it should lock when on backwards), two internal circuit board switches (mono/stereo and low/high power mode) the low/high power switch is hidden and not easily visible. It is a little awkward to have to access circuit board switches to adjust these settings. Overall very happy with the product.

[2x AAA] Great little amp stand, albeit takes a little getting used to in order to properly open and operate, and, the top back brace may get in the way of power cords on small amps e.g. the Peavey KB1 power cord is obstructed by the cross member brace however I fixed that with a 12 inch 2 X 10 board laid on the stand just under the amplifier. I purchased 2 and will not return them cause they are good but I wish I had purchased a tilt back tripod guitar amplifier stand.

[Single Channel] This is the best personal wired in-ear amplifier.
Great spund quality, balanced input or stereo input (configurable). XLR and TRS input... all that you need for an excelent wired personal in-ear monitoring.

[0.46 lb] Solid, easy to use. Packs compactly. I've seen reviews on other sites
where folk were trying to tighten the nuts/bolts... this isn't necessary. Lay the stand flat on the ground, and then lift one of the amp-support sections, rotating it about 3/4 of the way over. Repeat the opposite with the 2nd amp-support section. There are metal tabs which will hold everything securely. Great product at a reasonable price. FYI same is true for both the RS6000 (I use with a Tweed Pro 5E5) or the RS4000 (Blackface Princeton, Tweed Deluxe 5E5, or Vibrochamp)

[Single Channel] Bought to use with a standard headphone amp for live stage monitoring. Worked perfectly for my situation. Perfect enough I retired my 20 year old headphone and ordered the Fischer Amp2.
