READERS’ LETTERS: Switch mode versus traditional power supplies

A member writes: My new Class D GaNFET amp (Starkrimson Ultra) has dual mono SMPS that are deadly quiet (very black backgrounds), provide tremendous headroom (1000wpc clean peak power-4 ohms), and produce sonic realism and presentations that are jaw-dropping Live…all with a Total package weight of just 18#! 😉 —//— A member writes: Almost every […]

READERS’ LETTERS: Does the CD layer of an SACD sound better?

A member writes: I think in order to store a DSD recording onto a disk it has to be stored on a SACD disk and played back on an SACD capable player otherwise if played on a standard CD player you would only hear the standard pressing and not DSD. —//— A member writes: SACD […]

READERS’ LETTERS: Understanding series and parallel speaker connections

A member writes: Damping Factor(DF) is equal to the impedance of the load divided by the out put impedance of the amp. For example if an amp has an output impedance of say0.1 ohms and the speaker is 8 ohms the DF is 80. If you have 2 8 ohm speakers in series the total […]

THE PERFECT SPOT: Your seating position IS compromised

Paul McGowan … If you’ve done your system setup homework your chair sits at a comfortable distance from the loudspeakers. With the precision of a ruler, you’ve tweaked and adjusted the speaker’s position for best imaging. Though we call it the sweet spot, it’s certainly not the perfect spot. Within the boundaries of most rooms, the perfect […]

EXTERNAL vs INTERNAL / Is it better to have the loudspeaker crossover inside or outside the loudspeaker?

PAUL McGOWAN / PS AUDIO I was recently asked an interesting question. Is it better to have the loudspeaker crossover inside or outside the loudspeaker? At first, the answer seemed rather simple. Inside, of course. Shorter wires, fewer binding posts, etc. Yet, in thinking about it, I can see at least one advantage to an […]

UNDERSTANDING: Image height

PS AUDIO: It is not difficult to imagine left, right, and center imaging on a stereo system. It’s also likely not too much of a stretch to understand depth. After all, a proper stereo recording reproduces depth as a measure of how far away from the recording microphones the instruments or performers are. Harder for […]

VINTAGE AND / OR JUST NOSTALGIA: Do modern speakers sound better than vintage?

CF writes: On balance, I’d say yes. But it’s not an easy question to answer because it depends on so many factors. Which speakers are we comparing? Are we taking the used price of old speakers against what can be bought new for the same amount, or are we inflation adjusting the old price for […]

UNDERSTANDING: Room calculations

PAUL McGOWAN Our rooms are as important as our equipment yet only a scarce few of us have the luxury of choosing our room dimensions. Typically we take what we can get within our home and make the best out of it. With our new building in process, we’re heavy into the architectural tasks of […]

DOUBLE DUTY: For those that have receivers or integrateds with dedicated RCA subwoofer outputs, this post may have some interest.

For the most part, a dedicated subwoofer output on a receiver or integrated exists because of old-school habits. Long ago, at the beginning of the subwoofer era, there were no built-in crossovers. Subs came in two flavors: an unpowered or powered woofer in a box. If the first the user had to supply a power […]

ROOM TREATMENTS:

There are many multi-driver speakers, but few that go floor to ceiling like the IRSV. Floor to ceiling multi-driver speakers are called a Line Source. What’s counter-intuitive about a line source is how specific the imaging can be. With that many drivers, one would think the image would be tall, rather than lifelike, when the […]

SPEAKERS / AMPS: A beginners guide to bi-wiring

Jim Lesurf writes:  “Bi-wiring” is a controversial topic. Some people are quite certain it makes an audible difference. Some others are convinced that it can’t actually make any difference at all. The purpose of this analysis is to try and decide whether it is at least theoretically feasible that bi-wiring can make any difference. To […]

ROOM or SPEAKER? There seems a persistent notion that rooms need to be of a certain quality in order to take full advantage of what a speaker has to offer.

If your room isn’t good enough then investing in a wonderful pair of speakers is a waste of resources. Kind of like the idea that if you’re not a gourmet you cannot appreciate fine food. Poppycock. Of course it is true our rooms play a huge role in helping and hurting our HiFi system’s performance. […]

PS AUDIO: The significance of the folding transmission line in a loudspeaker?

What is the significance of the folding transmission line in a loudspeaker? My guess is that not many of you have heard of a folding transmission line in a loudspeaker, much less ever heard one working.  The late Bud Fried, from Fried Audio (pronounced “freed” as opposed to what one might do with eggs), was […]

SPEAKERS: It is, after all, an illusion

The center image of a two-channel system is known as the phantom channel for a good reason. It is an illusion. It doesn’t actually exist. Once you realize the center channel is completely dependent on setup, room, and speaker placement, it becomes a lot easier to purposefully do whatever it takes to enhance the palpability of your […]
