A Visit with Mik Bhavnani of Unique Audio UK

By | November 16th, 2019|Categories: Positive Feedback|Tags: , |

A legend has been running in the UK audio scene for many years, of an audiophile with a vast collection of the world’s most sought after turntables, amplifiers loaded to the brim with platinum transformers and rare vintage capacitors, and an audiophile lair with a sound that eclipses them all. For a long time I admit that I could scarcely believe that such an individual and system existed, and the whole thing must be an audiophile myth. As a keen angler myself, I have certainly grown accustomed to artistic license and outright myths on the river bank.… Read the full article

The Audio Equipment I Regret Not Having Bought, Way Back When (Part 1)

By | November 12th, 2019|Categories: Positive Feedback|Tags: |

Audio friend and brother John Marks, he who writes The Tannhauser Gate, takes us along on a remembrance of audio things past. His list is very interesting, and includes a favorite or two of mine, as well.

Enjoy the ride!

Regrets, I have a few… even about reviewer-loan audio equipment I now wish I had bought, way back when.

Wilson Audio & VTL

As usual of late, the Wilson Audio/VTL room did not disappoint…quite the contrary. The Wilson Audio Sasha DAW loudspeakers and their accompanying Wilson Watchdog Subwoofers, with an external crossover, were sounding quite full-range and authoritative, driven by the VTL S-400 Monoblocks. Shunyata, Roon, and dCS were also in this room. The Sasha’s have really been catching my attention over the past year; I’m keeping an eye and ear on them in 2020.… Read the full article

Introduction:  RMAF at a major new site

After a hiatus of three years (2016-2018), during which my colleagues Dave and Carol Clark headed up show coverage for Positive Feedback at the Rocky Mountain Audio Fest, it was time for Lila Ritsema (PF‘s Business Manager) and I to return to the big Mile-High. I had attended every RMAF from 2004-2015, with the sole exception of 2008 when I was briefly in Virginia.… Read the full article

Steinway & Sons Streaming: An Excellent No-Cost Music Source

By | October 12th, 2019|Categories: Positive Feedback|Tags: , |

Our good friend John Marks of The Tannhauser Gate continues his collection of re-published essays here at Positive Feedback. In this one, he makes us aware of a wonderful musical resource in the online archive of recordings from none other than Steinway. What a fine and generous opportunity this is!

Many thanks to John for bringing this to our attention.

The Duelund-Altec Project – Dare to Dream!

By | October 1st, 2019|Categories: Positive Feedback|Tags: , |

This particular feature article for Positive Feedback isn’t your typical audio review, but rather is intended to be a fun and inspirational “dare to dream” article that is decidedly outside of the usual audio mainstream.

This is an article that tells the story of the successful marriage of the latest state-of-art Duelund Coherent Audio CAST tinned-copper capacitors, inductors, and resistors—in a Jean Hiraga inspired crossover circuit (photo below)—with the historically important vintage Altec loudspeakers that were custom made for the domestic use of conductor Leopold Stokowski in the early 1960s (hereinafter referred to as the “Stokowski” Altecs).… Read the full article

John Marks of The Tannhauser Gate shares his reflections on the 50th Anniversary of the release of The Beatles masterpiece album, Abbey Road, by reminding us of George Benson’s follow-up LP, The Other Side of Abbey Road. In the midst of the celebrations that Philip O’Hanlon has organized at a high-end audio dealer level, very many of us are receiving or awaiting the arrival of the new remix and reissue set of this musical wonder.

As we should! Read on…
