LSA VT-70 TUBE INTEGRATED STEREO AMPLIFIER/HEADPHONE AMPLIFIER REVIEW

April 17, 2022 Comments Off on LSA VT-70 TUBE INTEGRATED STEREO AMPLIFIER/HEADPHONE AMPLIFIER REVIEW

To perform my listening tests of the LSA VT-70 Tube Integrated Stereo Amplifier/Headphone Amplifier I used my Audio-gd R2R-1 DAC as source, powered by a Core Power Technologies A/V Equi=Core 1000, and for cabling Cardas Iridium single-ended RCA interconnects, Cardas Iridium power cords, and a Cardas Clear USB cable. LSA recommends letting the amplifier warm up for about half an hour before listening for best results. This may seem like a long time, but truth is solid-state amps can take several days to reach full operating temp, for this reason, the amplifier that is now running my AV system has only been powered off during the last 40 years, for moves, system changes, and power outages. One further step I went through before doing any serious listening was to re-bias the tubes. While strictly not necessary as this was done at the factory, tubes can change over time, and environmental factors, as well as the effects of shipping, can cause this to change. As it turned out, the bias was a little high, not critically so, but worth noting. Due to space considerations, I set up the VT-70 on the far side of my desk facing away from me, so the remote control came in real handy.

PureAudioProject Trio15 Coax10 open-baffle speakers $8,250 Review

April 17, 2022 Comments Off on PureAudioProject Trio15 Coax10 open-baffle speakers $8,250 Review

The Trio15 Coax10 does not accomplish the full range, single point source sound signature perfectly. It obviously cannot, as there are two huge 15” woofers flanking the 10” driver. The ear perceives this, especially when bass-infused music is heard. However, this is not a problem, except for those who are willing to eschew lower frequencies in search of a perfect point source sound. You simply cannot have it both ways; the closest you can come is with a speaker like the Tannoy Glenair, which I reviewed back in 2008. But like the Glenair, with the Horn1 you are making a more difficult match of the 1.4” polymer tweeter to the 15” woofer. It works, and to many persons’ ears is a splendid result. But, by necessity, it leaves some room for improvement in the midrange and mid-bass, and that is where the Coax10 shines.

One of my system-building principles is that unless absolutely necessary, I will not be without deep bass, and ideally not without LF, i.e. lower than 20Hz from high-resolution audio files. I see those frequencies as necessary to grasping the extent of the performance. If it is a choice between having the pure point source with only a 10” driver or the PAP design with assistance from the 15” drivers, I will opt for the presence of the 15” drivers, because elimination of the bigger drivers forfeits not only the reproduction of those low frequencies, but also the potential for the tactile sense created by deeper and stronger bass. I do not wish to have a large set of forward firing open-air headphones, but a speaker system!

Estelon X Diamond Mk II $83,000 Loudspeaker Review

April 16, 2022 Comments Off on Estelon X Diamond Mk II $83,000 Loudspeaker Review

I think my assessment of the X Diamond Mk IIs is clear. This is not just one of the great floorstanding, direct-radiating loudspeakers; it is one of the greatest floorstanding, direct-radiating loudspeakers. Its relatively modest size (four-and-a-half-feet tall, a foot-and-a-half wide) and beautiful (and beautifully functional) shape make it ideal for modestly-sized-to-larger rooms (though Estelon’s bigger—and just as beautiful and innovative—transducers may better suit truly large spaces). Obviously, I recommend it. Indeed, I can’t recommend it highly enough. Which is why Alfred Vassilkov’s Estelon X Diamond Mk II is the 2021 winner of The Absolute Sound’s foremost honor, the Overall Product of the Year Award.

Chord Anni Desktop Amplifier Review

Is it a mini-amp with a fine headphone output, or a ‘head-fi’ design also capable of driving small speakers convincingly? However you look at it, Chord’s Anni is a great choice for desktop audio with a sound tailored to flatter partnering equipment. It’ll drive bigger, sensitive speakers at a push, but that’s not its role – the Anni ‘is what it is’, to quote an overused cliché, and looks and sounds well-judged for its tasks.

The LSA Signature 50 Speakers


There’s a cost to play because Underwood HiFi isn’t Amazon, Best Buy, or Nordstrom. If you don’t like the Signatures enough to keep them, there’s a 15% restocking fee. And you’ll have to pay to ship 50 pounds back. But remember, experience is what you get when you don’t get what you want, and everyone has to keep the lights on.

If the description of the LSA 50 Signatures ticks your boxes, you probably won’t want to send them back. That said, these are worth rolling the dice for. Should your system grow beyond the roots you plant with the LSA 50 Signatures, you’ll probably keep them for a second system or to pass on to your kids or a friend about to start their audio journey. They are that good.

Audio Research Reference 80S stereo power amplifier Review

April 14, 2022 Comments Off on Audio Research Reference 80S stereo power amplifier Review

That consistency is the joy of this amplifier. If you have a yearning for Big Boy Audio Research, but don’t want or need the additional power and the increased size, space, heat and price tag that top-end amplification requires, the Reference 80S is perfect. Making a bigger amp smaller is often a path to being disgruntled, or at least puts you some way from being ‘gruntled’. This is the first step on the Audio Research Reference power amplifier ladder, and I can’t help but feel that while it is for many the only step they’ll ever need to take, for others the excellent Reference 80S will be the first step into a world of the highest in high-end audio

Constellation Audio Inspiration Integrated 1.0 amplifier Review

April 12, 2022 Comments Off on Constellation Audio Inspiration Integrated 1.0 amplifier Review

If it excels at the big and complex, then it is equally impressive on the seemingly simple. ‘Wayfaring Stranger’, the classic American folk tune from Grateful Dawg [Acoustic Disc] by David Grisman and the late Gerry Garcia is a simply arranged live recording with a couple of gloriously out of tune vocals that is so compelling because of its sheer reality and straightforward instrumentation. It could hardly be more different from Bill Laswell’s Divine Light but it is no less compelling. The Constellation shows what a charmingly intimate amplifier it can be. It even makes a banjo sound good and that will do for me. The song is from Grateful Dawg which is not an offering that has undergone much in the way of studio mastery or post-production enhancement, I would think. But it’s the straight-up charm and, of course, the quality of the playing from the guys and their bluegrass sidekicks which make it so real and so interesting. The Inspiration Integrated 1.0 just lets it all through. Atmosphere all the way but very different indeed from another largely acoustic album that has charmed me. Julian Lage is, I believe, one of the finest guitarists on the planet at the moment, electric or acoustic, and I am particularly fond of his collaborations with Chris Eldridge. On Avalon from 2014 [Modern Lore] they use a simply recorded, dry acoustic space to demonstrate some stellar musicianship and show just how expressive, versatile and real this classic format can be. The Constellation showcases the wealth of tonal shading, stunning clarity and texture that these two embellish through thicker, wound strings to breathe life and touch-ability to the music. The speed and eloquent note control plays right into the amplifier’s considerable strengths and illustrates exactly how to tell a story through an instrument. I’ve never heard it sound better.

Lab 12 integre4 Audiophile Integrated Amplifier Review

April 11, 2022 Comments Off on Lab 12 integre4 Audiophile Integrated Amplifier Review

https://www.audiophilia.com/reviews/2021/10/26/6difo4beq7hy6zrt1kyjbzb1nfk45a

As you can see from the promotional images above, the integre4 is a good looking integrated amplifier. It has excellent sound and is very easy to use. It will grace any listening space. It’s not especially ‘tubey’, but does present as typically pentode. However, lovers of tube designs will enjoy the emotion the integre4 bestows on the music. And if swapping tubes is how you roll, the integre4 is your guy.

Lab 12 is now 10 years old, and, as they transition into their next generation, you can be sure you are getting quality production and fine design from a Greek audiophile with his listening ears on. Highly recommended.
