Nelson Pass – The Patents Of Pass

Brian Damkoroger: If high-end audio were to carve its own Mt. Rushmore, whose faces would appear there—besides that of Stereophile founder J. Gordon Holt, of course?

TO BE … OR NOT: Bi-amping?

PAUL MCGOWAN … There once was a day when power amplifiers struggled. The mainstays, tube amplifiers, couldn’t handle low frequencies well but had immaculate highs. The newcomers, solid state amps, produced prodigious bass but struggled with the high notes. None handled both. That’s when some bright person decided to combine the best of both worlds. […]

MARANTZ / ROWLAND: Classic 9 + Rowland Coherence, hot pins on XLR connectors.

Can I use other tubes than the EL34s on the Marantz 9s? The amps themselves and the manuals are marked with those specific tubes. So I don’t know if tube rolling would create problems. If you feel it’s technically possible and advantageous, what would you recommend in connection with the Quads?  Also, a phase issue […]

LFD AUDIO: Q&A … damping factor

Howard writes … A question of mine, to address my inquisitive nature.  My preference, for most types of music and most speakers is a high damping factor. I value speed, agility and articulation over heft, weight and so on.  To date, the PA2M(SE) is the most satisfying I have heard. Hypothetically, is it technically possible […]

MERIDIAN: Thoughts invited re a curious phenomenon re pre-owned gear

 Howard Popeck … There has been for some while a curious trend re the sale prices achieved for BS Meridian pre-owned equipment. The 500 series and 600 series do attract rather high prices whereas the G-series rarely do. Even the comparatively modest 200 series, now circa 28 years olds, achieves surprisingly high prices.

COLIN WONFOR’S TECHNICAL CLINIC: How to judge an amplifier’s performance with a “powered-woofer” speaker?

QUESTION: Hello Colin, I can’t seem to find a definitive answer.  Nowadays, many speakers are made with a built-in woofer amplifier. Vandersteens, Martin-Logans , Von Schweikert, etc. How will an amplifier affect the tonality or dynamics of this type of speaker? COLIN WRITES … This is normally done to stop frequency interference of the high and low sounds, […]

MYST: TMA3 – a few observations by Howard Popeck

Way back in the early 1980s at Subjective Audio I sold quite a few of these. They retailed at around £290 inc vat. It was then, and even by today’s standards a minimalist design. The case was nothing special. In fact somewhat uninspiring. The inside though was, as was the buzz-word of that era “something else” A text book example of well-built design with excellent attention to detail. Frankly, extraordinary for both the time and the price.
