Wells Audio Commander Preamplifier Review

By | September 16th, 2019|Categories: Dagogo|Tags: |

Years after selling them, I still wonder occasionally how could I have divested my pair of Wells Audio Innamorata amplifiers. At the time it seemed necessary, as I was making a purchase of some speakers. Over time, as I continue to review components, I recall how many gorgeous systems I made with those amps, and I find it hard to avoid self-recrimination.

It came as no surprise, then, that when Jeff Wells contacted me in order to fulfill a years-old promise, he had my attention.

Linear Tube Audio's Microzotl Preamplifier and ZOTL40 Reference Amplifier

By | September 11th, 2019|Categories: Positive Feedback|Tags: , , |

Prologue: A Berning Desire

Many years ago, I purchased a boxy little bespoke headphone amp for my Sennheiser HD600’s called a MicroZOTL. Built by a mysterious mid-Atlantic, not-so-mad audio scientist by the name of David Berning, the MicroZOTL was a mighty tiny wonder. I loved it so much I had physicist / audio manufacturer Berning build me his ZH270 integrated amplifier. It was a great amp. Mr. Berning’s creations are aural artworks to be treasured, but sadly, those were early days in my own high-end audio journey when I was continually choosing to try different paths, and I eventually sold both amps to lucky audiophiles.Read the full article

Paradigm Persona 7F loudspeaker and Persona SUB, Anthem STR preamplifier and STR power amplifier, Wolf Alpha 35X server, Torus RM20 power conditioner, Clarus Aqua cabling.

By | September 10th, 2019|Categories: Stereophile|

Paradigm’s Canadian-designed-and-engineered Persona 7F loudspeakers, which have beryllium diaphragms, anchored a system that received additional grounding from the Paradigm Persona SUB ($6500). The sub’s six 8″ woofers are powered by a 1700W “Ultra Class D” amplifier that, aided by DSP and other stuff, descends to a formidable 12Hz.

The room also featured the premiere of the production version of the Wolf Alpha 35X music server ($9295), which was previously shown at the Hong Kong show in prototype form. The company’s Joe Parvey told me that the 35X includes $1200 retail worth of Stillpoints products, including patent pending ground plane enhancement.… Read the full article

Backert Labs Rhumba Extreme 1.3 Preamplifier: A Neutral Presentation That Excels in Micro Dynamics and Harmonic Delicacy

Dr. David W. Robinson, Editor-in-Chief

In my humble opinion, the two most under appreciated aspects of high-end audio are room acoustics / speaker placement and the preamplifier. These are the unsung heroes of the best sounding audio systems in the world. Speakers are generally front and center—kind of like a quarterback for a great football team.… Read the full article

Allnic Audio L-7000 Preamplifier

By | August 30th, 2019|Categories: Audiophillia|

public.jpeg

David Beetles of Hammertone Audio, the North American distributor for Allnic Audio electronics, gave me a nod that an L-7000 Preamplifier was available for review. The new linestage is the $16,500 replacement of the L-3000 ($13,900). After my continuing musical experiences of the most passionate and intense kind with Allnic’s similarly priced H-7000 Phono Stage, how could I pass up the opportunity to hear Allnic’s linestage equivalent?

The L-7000 is not your grandpappy’s 300B tube linestage preamp. It is a single gain stage unit and is transformer coupled.… Read the full article

McIntosh C2700 Preamplifier

By | August 25th, 2019|Categories: AV Hub|

McIntosh’s latest C2700 valve preamplifier incorporates the company’s new DA2 Digital Audio Module to add upgradeable digital music capabilities to the pre-amp’s analogue inputs. (Click images to enlarge.)

We’re Gonna Spread Our Wings And Take To The Sky

For some time now I’ve been attempting to implement, to my satisfaction, a home built music server/home theater PC. Being an audiophile, I set the bar higher for sound than picture. But until just recently my attempts have not produced sound quality competitive with my universal disc player. In fact, I could burn the files from my computer to a CD rom, compare the sound directly from the computer with the burned disc in my player, and the player always won easily.… Read the full article

Pro-Ject Audio Phono Box S2 phono preamplifier REVIEW

By | August 21st, 2019|Categories: AV Hub|

This unassuming little box, just 12cm wide and 3cm high, can have a profound effect on your hi-fi sound. It’s an offboard phono stage, an amplifier dedicated to the output of a turntable, raising the tiny signals generated by the stylus and cartridge up to the levels required for the line-level inputs of an amplifier.

Equipment
The Phono Box S2 is part of Pro-Ject’s S2 line, and is described as the company’s ‘Best Buy’ phono stage; there is one below it in Pro-Ject’s range but several larger and more complex-looking phono stages above it in the company’s DS2 range, including models which use valves.… Read the full article
