Review: Best budget amp for Sennheiser HD800S - If you own the HD800S and want to explore tube amps, I wouldn't walk but run to try this. I previously used the Massdrop x Eddie Current ZDT Jr but decided to buy this amp based off a recommendation on the Super Best Audio Friends forum. After comparing the two, I sold the ZDT Jr and kept this amp as I enjoyed the sound of it more in comparison. Compared to the ZDT Jr, this amp's bass impact is noticeably stronger, fixing what I always felt was the HD800S’s biggest weakness. But, the trade off is a slightly smaller soundstage, and for me, that’s okay. Treble is also slightly rolled off which helps with the HD800S' second weakness which is sibilance. The overall sound with this amp is smooth and impactful. There are two downsides to this amp. First is that the power button is in the back of the amp. It's a minor inconvenience to have to reach to the back to turn it off and on but I can live with it. Second is the humming. If you're experiencing humming, I would check to see if it's caused by the front tube. In my case, tapping the front tube with a remote control permanently fixed the problem (similar to fixing old TV static back in the day by tapping the TV). Your mileage may vary, but it’s worth trying before assuming the amp is defective. Despite the inconveniences, given the price, I would highly recommend this amp. If you’ve been searching for a budget amp to pair with the HD800S, this could be your endgame honestly. I've previously owned the Schiit Magni, Cavalli Audio Liquid Carbon (remember that amp?), and the Massdrop x Eddie Current ZDT Jr and this amp blows all of them out of the water. Review: Loud transformer noise - UPDATE: The seller and manufacturer took a fast response and sent a second unit, which is working perfectly well. Noise floor is acceptably low and the sound impact is amazing, I use this unit as a preamp/buffer for a small JLH1969 2x15W Class-A solid state amp, the combination not only has full bass but also very clear and defined mids and non-fatiguing highs. Overall I am very satisfied. PREVIOUS: When I power on the amp, the transformer immediately start making a loud buzzing/humming sound that can be heard across the room. If I connect it as a preamp, the same noise is audibly amplified by my power amplifier, resulting in a very disturbing bottom noise. Although it colors the sound the way I wished it would, making the soundscape more vivid and with fuller bass, I don't think I can use this item with the constant hum it generates. ## Features - 6N2 TUBE FOR PRE-AMPLIFIER.
