I hope the designer sees these measurements and at least works to sharply reduce the power supply noise as that can't be anything good no matter what school you are from.Īs always, questions, comments, recommendations, etc. Needless to say, I can't recommend the Vista Audio Spark II amplifier.

Acts as a Bluetooth speaker at the same time as an amp for playing along. There must be some mystique about it that I don't understand. Vast number of user-created sounds to explore. This amp has too little power to drive most speakers and has a lot of noise and distortion as well. Sometimes I really wonder what appeal such amplifiers have that attract buyers. It did better actually with 8 ohm load indicating current delivery is its issue:īack to 4 ohm, if you allow more distortion or bust the input, you do get a bit more power:įinally, there is fair bit of variability when we sweep frequencies: The amplifier is rated at only 20 watts but I was not able to get that: Multitone shows a messy response with the lows polluted by the power supply and highs due to inadequate feedback: I was surprised to see a bass roll off in this day and age where just about every amplifier is dc-coupled: There are various models available, including the original Spark and the newly-announced Mini version, but the best value amp right now is the Spark Pearl, which is currently available with up to £46 off, including a.

Over the last couple of years the Positive Grid Spark has revolutionised the ever more competitive guitar practice amp market.
Signal to noise ratio is better than what we saw in the dashboard indicating the noise floor rises with power: Spark Amp Review It’s important to stress further how practice amps have come a really, really long way. As a result, the amplifier rates quite low in our overall ranking: Even if that was low, the distortion spikes are not. Playing with grounding reduced the spikes at 60 Hz a bit but did nothing to the harmonics which are caused by the internal power supply. I had to crank the volume all the way up to get close to my nominal 29 dB gain (per THX spec):īoy, that is a lot of power supply noise. Is this the first audio product we have tested from Serbia?
Doesn't matter if the performance is good anyway. Would have thought to put the IEC jack all the way to the left and speaker to the right. The rear of the amp is a bit unusual in placing the mains input between the connectors: Nice to have dual inputs and volume control. The Spark comes in a deep but otherwise small case: It was kindly sent to me by a member and costs US $389 from the company direct.
