Puritan Audio Ground Master Ultra City

Dealing with Nick is always a pleasure. AAA+

The least “electronic “ sounding moving coil I have used. Not as extending in the high frequencies or as detailed as the Lyra Kleos, but very natural sounding in the midrange. Low frequencies have a nice bloom, imaging is very good.

Excellent music playback

Great services

Really great holographics and bass. really worth the bucks in nearfield

Great packaging and fast delivery.

Amazing product, great packaging and fast delivery.

The device was delivered in a perfect condition with extra care. I was totally satisfied with the service.

The device was delivered in a perfect condition with extra care. I just tried the Valkyrie with some of my IEMs. Its sound characteristic is similar to PCM 1795DAC but a little warmer. Still, it does not lose any details. Amp is not only powerful to drive my receivers smoothly, but also capable of delivering dynamics of songs with handling volume differences over all frequency ranges. Overall, great service and great device.

Great! Very responsive and helpful, item arrived as described.

Very Well done.

Fast shipment and professional service from Nick.

Awesome experience. Quick responses to Q’s and good selection of products. Would definitely recommend.

This thing is amazing. Nice sound stage, good details but not fatiguing and very neutral in its presentation. Presently pairing it with the Aegis headphone amplifier (tube) & Senn headphones and this combo is super solid with the Z10. Lots of really nice features in the Z10, from filters to allowing use of external master clocks. You really can’t go wrong.
