Lumin T3X streamer-DAC: Do QRONO and LEEDH Matter?

Streamers and Digital to Analog converters are the key source for modern high-end audio systems. For most people at least, if for no other reason than the availability of nearly the entire catalogue of recorded music. And ease of use. And low cost. What can be confusing is the degree of sonic difference between various streamers – devices that request music from a streaming service and convert the music files from network protocols to music file types – and various DACs – devices that convert digital signals to analog signals that amps and speakers use. They’re just computers dealing with files. Simple, right? Well, no, apparently. Which brings us to the Lumin T3X with QRONO and LEEDH technology. Right now, I’d rate this as the lowest cost way to get 95% of more of what digital can do. It isn’t inexpensive, but I think it is a benchmark that helps everyone think about audio system building and budgeting.

Sennheiser HDB 630 Wireless Headphones Review

Flexibility is not something one usually associates with wired headphones. After all, you're tethered to your equipment. You can't go out, hop up and get a cup of coffee, and you can't do a lot of adjustment to the sound profile as well. Wireless headphones promise to do a lot more. Aside from the flexibility of being able to get up and move around, that will without a cable tied to your head. But also the idea is you could adjust the sound to your own personal specifications, as it were, because wireless headphones have digital signal processing on board. So if you need to, you could tweak the sound. The trouble is, in cutting the cable. Obviously a lot of the sound quality got cut as well. Sennheiser now has tried to solve that problem with the HD630s.

Isoacoustics GAIA Neo speaker feet

In this briefing, I give my basic observations about the performance of the Isoacoustics GAIA Neo speaker footers. These are complex passive absorbers that replace the spikes normally used at the base of speakers like my test subject, the Perlisten S7t. Normally, I think of products like this as “below threshold” items – products that may be beneficial, but whose effect may be difficult to hear in isolation, especially because a quick A/B comparison is hard and the effect is subtle. But I heard a demo arranged by IsoAcoustics that suggested otherwise, and when they offered to supply a set for testing, I accepted because in my listening room I have much longer to understand what products do. Let’s see what I found.In memorium: Dan Roemer: September 4, 1970 - December 26, 2026Dan was the genius behind the S7t speaker mentioned in this video. He was a great designer and a special person. He will be missed.

Monitor Audio Studio 89 Bookshelf Speakers Review

There's a lot of nostalgia out there for the 1980s, and when British speaker maker Monitor Audio looked back at that decade, it discovered gold in the form of its studio 15 speaker. And so, inspired by the creativity and individuality of the 1980s, monitors set out to create the studio 89. So are these $2,750 per pair speakers totally awesome or just bogus?

Orchard Audio Pecan Pi+ Premium Streaming DAC Review

Orchard Audio is a US manufacturer of amplifiers, headphone amplifiers and now streamer/DACs in the case of the product we’re reviewing here, the Pecan Pi+ Premium. The company believes strongly in engineering and is particularly sensitive to leveraging appropriate parts. We’ve reviewed their Starkrimson GANFET amplifer previously. With the Pecan Pi, we were particularly attracted by the incorporation of top, and relatively rare, AKM Velvet Sound filter/modulator and DAC chips. But there is more to the design. Let’s take a look.
