FIIO K5 PRO $149 Review

January 26, 2020 § Leave a comment

“You may not notice the upgrade on the outside, but this is a great feature that allows much more precise low-volume control, letting you enjoy sensitive IEMs in a quiet environment also to use the K5 Pro as a volume controller/ Preamp for powerful power amps.

Channel balance issues have always been a nightmare for mid-night listens especially with multi-ba IEMs and sometimes it may get too loud before you find the sweet spot/ minimum vol. that works, if you have very sensitive ears this may be a great feature.”

Dan D’Agostino Master Audio Systems Progression Stereo Amplifier and Preamplifier $22,000 Review

January 25, 2020 § Leave a comment

“The power amplifier is, well, a power amplifier. Aside from a large front-panel meter, with some fun color options, it has no special controls. The only practical feature I’d flag is that the amp has XLR inputs only, but few audiophiles today are going to use RCA cables in any case. Like all good power amps, you put it in place, hook it up, turn it on, and forget about it, although you will want to run a mini-cable between the preamp’s 12V trigger output and the power amp’s trigger input so that the amplifier turns on automatically with your preamp. 

This is not just an ordinary power amp, however. When D’Agostino uses the word “power,” he is not kidding. The Progression stereo power amp is a 125-pound unit that can deliver 300 watts into 8 ohms and 600 watts into 4 ohms. Its gee-whiz technical features include 42 output transistors, a nearly 3000VA power-supply transformer, and 400,000 microfarads of power-supply storage capacitance, and it can optionally be hooked up to a 240V AC socket.”

Bose To Close HALF of Their Retail Stores Worldwide

January 24, 2020 § Leave a comment

“Bose Corporation, a leading manufacturer of headphones and other audio equipment announced that they will be closing HALF of their retail stores worldwide due to a dramatic increase in online purchases. Although founded in Massachusetts in 1964 by Amar Bose, the first retail store was opened in 1993 in Kittery Maine.  Bose was founded on creating speaker systems which used multiple drivers aimed at the surrounding walls to reflect the sound to replicate the sound of a concert hall, it has diversified its products to include smaller portable speakers, earbuds, and the highly promoted and profitable sports, military, and consumer based sound cancelling over the ear headphones.”

“In fact, the Sasha DAW’s only real weakness is possibly also its greatest strength. This is not a loudspeaker that ever sounds bad (its greatest strength), but it also has the potential to sound truly soul-shakingly good. There will be some pairs of Sasha DAWs where that potential remains untapped. This is a loudspeaker where going to the extra place is not simply an exercise in navel-gazing but returns the kind of performance that can stop you in your tracks. Here’s a perfect test of the Sasha DAW’s true power; play something evocative like Jacqueline du Pré’s remarkable rendition of the Elgar Cello Concerto [Barbirolli, LSO, EMI]. Unless the system has been set-up with a pick-axe, you will get goose-bumps. When the system is fully on song and at its very best, you find yourself in tears. It’s an uncontrollable, almost atavistic, reaction to the music that happens when the system pulls the music into focus. You can find this in very well set-up systems, but usually in very well set-up systems that cost so much they could depth-charge the economy of a small island nation.

Meze Rai Penta Review

January 23, 2020 § Leave a comment

“I call out this track particularly because it is recorded outside, so it has that kind of dry ambience outdoor recordings have, and it is hyper-detailed and dynamic with fairly gentle limiting. My initial impressions were that the Rai Penta was editorializing a little on the transients – that I wasn’t getting as much impact as some recordings. My impression of this was due to the aforementioned lack of pressure I was hearing on this IEM. The “Woods” track, and say the Peter Dominguez Track “Bossa Nova Nemo” actually have plenty of transient and dynamic information, so I after listening to these I came to a different conclusion entirely. I think what I’m hearing is a what might be considered a very ‘open’ decay characteristic, similarly to the difference between open and closed headphones.”

iFi ZenDAC Review

“While that might sound relatively modest compared to smaller desktop amps which now routinely offer several full watts of power, there’s been a bit of confusion about what exactly the result of that is. More power does not determine a system’s volume – that is in fact determined by gain. A lower powered amp will actually sound louder than a higher powered one if it has more gain at a given input. Power is more important in determining what the maximum current or voltage a device can swing into a transducer when hit with musical peaks as well as how loud waveforms are. So, think of power as being a rough indicator of how dynamic a system can be, and gain as determining its relative loudness when listening. I’m grossly oversimplifying and all the electrical engineers are squirming, but I think you get the point.”
