So I say base your purchase decision on company reputation, form factor, looks, availability, etc.įor now, the Monoprice Liquid Spark gets my recommendation.Īs always, all questions, comments and criticism is welcome. Listening tests show the three in dead heat with essentially nothing differentiating them. The other two have more of a boutique performance with their distortion rise at low load impedances. The O2 has more of a textbook performance but slightly less power. It joins two other good products, the JDS Labs O2 and Schiit Magni 3. While there are a few oddities here, this is the first Alex Cavalli design that I have tested with competent performance and at hugely bargain price of just $99 including shipping. So I would say this is essential a three-way tie with a tiny nod toward Magni 3 at exceedingly high output levels. Without risking hearing damage, I could not push either amp further to cause any differentiation in delivery. I fixed that and the difference went away. At first I could easily hear change in sound stage and even fidelity but then realized that the channels were swapped in O2.
It undoubtedly elevates the digital modeling amps to another level with its innovative solutions. I then organized the same comparison against the JDS O2. Spark 40 costs around 250, and I would rate this amp 4.5 stars out of 5, maybe not because of its sound but because of its versatility and helpful, innovative features. I could not repeat this with any other tracks at exceedingly high playback levels. Finally on a bass heavy track at leaves approaching hearing damage, I managed to find one instance where the bass got distorted in Liquid Spark but stayed clean in Magni 3.
AB tests with either Sennheiser HD-650 and HiFiMan HE-400i did not show any audible difference at first. I played a tone and then level matched both using my Audio Precision analyzer. I connected both using a split RCA cable to my Topping DX3 Pro.
Review spark amp Bluetooth#
I started the testing by comparing the Magni 3 to Liquid Spark. For under 200, it’s hard to name a guitar-playing tool that I like more than this combination amp and Bluetooth speaker. Regardless, we see the same lower power output and potentially lower noise if we just look at the good channel. The new Gear Drop available for all Spark users and includes a Dumble and Klon-inspired models see a demo here. Maybe the 3.5 mm jack is lose or something. This was weird as one channel in O2 became a lot more noisy.
