“The SOPRANO really sings! I had the privilege of hearing a Stack Audio Soprano LP12 for 4 hours yesterday and it sounds superb.. I was invited to listen to it by Richard, a new friend that I came across on another forum. We spent 4 hours listening to a wide range of music from Dire Straits to Norah Jones, Paul Simon to Roxy Music, Bruce Springsteen to Jennifer Warnes, Sade to many, many others. It handled it all effortlessly and sounded superb.

The Stack Soprano LP12 was fitted with a Supatrac Blackbird tonearm and DV XX2 mk2v cartridge along with a Lingo4 PSU. It was powered via a Rega Osiris integrated amplifier into Shahinnian Obelisk speakers.

I was also very impressed with the build quality of the Soprano LP12, it looked amazing.

As many of you already know, my own LP12 has many Stack Alto parts fitted and so it was very interesting to explore and listen to the Soprano. It certainly lived up to my expectations and coupled with the amp and speakers mentioned earlier it produced an extremely open and natural soundstage.

The bass and handling of the bass was outstanding, the midrange and highs were simply delightful. It was a system that simply made the smiles listening to it bigger and bigger.

From a construction point of view, IMHO the Soprano LP12 must rank as one of the the very best LP12 foundations that money can buy.

So just a quick heads up on my initial thoughts and a big well done to Theo for a remarkable product.”
