Violectric HPA V550 Headphone Amplifier

I have purchased the Pro model of HPA V550 headphone amplifier to be used with my Meze Empyrean headphones. The Pro model has an advanced relay-based volume control and it is really smooth and quiet. I already have an older HPA V200 and this is definitely an improvement - cleaner, more powerful and balanced. I have now ordered balanced headphone cables.

I would also like to thank PlayStereo for their service. This was my first purchase and shipment was from Italy to Abu Dhabi, UAE. To my surprise, I received it in only two days and it was the most efficient delivery that I have experienced during my 20 years in Abu Dhabi. Well done!
