eXtra Sexy Audio

XSA-Labs offers unique, innovative, and leading edge products for the very best in SOUND QUALITY with great pricing & the value Underwood looks for using state of the art design and manufacturing technologies. 
Their agile and forward-thinking design and management team has over 110 years of combined experience in the audio, electrical, and aerospace engineering fields.
Their products offer superior value products and great , might I say absurd prices. The Caldera 10 subwoofer and Scout monitors are their first 2 products. The Scout monitor, at $299.00 a pair, is a superb value. It is a real rosewood 2 way monitor with 5.25" woofer and soft dome tweeter. Initial press and customer feedback has been exceptional. There is also a new Virtual Black Hole isolation device that is a steal at only $199.00 for a 4 unit set. Great for speakers, amps, preamp or DAC's. A 12" 600 watt Rosewood Caldera sub is due next around the end of February at only $399.00. These will be followed by a 40wpc Pure Class A power amplifier and stereo preamplifier. See the renderings of the amp and preamp below. XSA products come with a 30 day trial with 20% restocking fee.

Vanguard Caldera 10" subwoofer

Here is the first review from Tom Gibbs, Positive Feedback:
"Sequence of events: REL subwoofer dies, resulting in worst day of the week. Vanguard Caldera shows up, and on day one, can things possibly get any worse? Day five following Caldera's arrival: Best day of the year!"
"I never, never dreamed in a million years that the Vanguard Caldera is literally the giant killer that it is;"
"And as great as a single Caldera has been for me, getting two of them makes such perfect sense, both from a financial and audiophile standpoint. Running dual subs will definitely help smooth out any in-room bass anomalies, and would lead to a significant uptick in system performance. At $199 for a single Caldera, your decision is a no-brainer; getting two of them at $199 each makes your decision completely idiot-proof."

"The Good: Seriously? Re-read this review! They say there's no free lunch in high-end audio, but with the Vanguard Caldera, you get an appetizer, lunch, dessert, and a craft beer. All for $199—it doesn't get any better!"

"How is it that Mark Schifter and Vera-Fi are able to manufacture and sell the Vanguard Caldera for $199? I'm beyond baffled, as the sub it's replacing (yes—it's definitely a keeper!) sold new 12 years ago for $1k, and would probably sell for close to twice that today. I'm blown away—yet again—by another of Mark's products: both Mark and his collaborator Viet Nguyen are definitely on their A-game. Well done! The Vanguard Caldera subwoofer comes very highly recommended!"

 Beautiful rosewood monitor speakers offer superb value. This is the class in the under $500.00 price range.

The Scout uses a 5.25" paper cone woofer with a 1" soft dome tweeter. The crossover is exceptional for a speaker on this price range. It is all housed in a beautiful real Rosewood enclosure.

The first review in Tone Audio was a rave. They said:

"Thanks to modern drivers, the Scouts seem very robust, and they possess a lot of the soul that this great American mini speaker (Spica TC-50) produced. A tremendous midrange, smooth highs, and mid bass accuracy instead of muddy mid bass, compromised to goose the low end. It’s hard to believe these are only $299/pair. Back when gasoline was $6/gallon, it cost more than this to fill up a Dodge RAM truck! Going further back, the Spica TC-50s were $450/pair."

"The Vera-Fi Vanguard Scout speakers are a true triumph for music lovers on a tight budget."

VBH-1 Vibration Black hole
$199.00 for set of 4

Read the initial Stereotimes review where they sum with:
To quote Mr. Schifter, “Real Deal Science at a humane price,” he’s spot on with that description.
Frankly, I didn’t expect quite this level of vibration reduction and isolation from such a cost-effective product. Vera-Fi Audio LLC’s VBH-1 Vibration Reduction Feet is an “easy lift” for even the most frugal audiophile to use under single or multiple components. Color me impressed!

Read the entire review here: https://www.stereotimes.com/post/vbh-1-vibration-reduction-feet-vera-fi-audio-by-greg-voth/

The Vibration Black Hole (VBH) isolation feet provides mechanical vibration attenuation and isolation using a novel two-stage constrained viscous layer damping (CVLD) technique whereby a compliant and viscous polymeric medium is placed in between two hard surfaces, thereby providing a mechanical impedance mismatch that dissipates the energy from mechanical motions/vibrations through the mechanical shear and compression of the viscous layer. By use of dissimilar materials (nylon/stainless steel/viscous polymer/silicone rubber) in multiple stages, the VBH provides an exceptional level of extra mechanical dampening between two components needing mechanical isolation. 

The VBH is ideal for mechanically isolating sensitive audio gear such as turntables, tube amplifiers, preamplifiers, and buzzing power supplies in large linear amplifiers. They are also very useful for isolating speakers from hard floors or tables to provide an improved soundstage and bass clarity. Each VBH consists of a precision machined stainless steel body and stainless steel inner core and a machined nylon piston-like conical contact pad. In between each of these components is the unique CVLD dampening compound. The device being isolated mounts on the included machined aluminum spike feet which mate to the nylon conical contact pads to provide the first stage of isolation. This stage is then in contact with the main external base through a second CVLD pad. The second stage of CVLD has an external backup silicone o-ring bumper to prevent bottoming out under heavy load and itself also acts as a CVLD under heavy loads. 

Each VBH can support up to 30 lbs so a speaker with four VBH can weigh as much as 120 lbs. The VBH has been tested with an instrumented turntable plinth and special instrumented and calibrated test hammer and has shown a significant reduction in the transmitted mechanical shock and reduction in transmitted mechanical energy. 

Series One A40- 40wpc pure Class A power amplifier
Due out in March
Pre-order now at the 1599.00 intro deal. Call with $100.00 deposit to reserve one

Originally called the A25 it is now the Series One A40 with 40 watts per channel

A chassis CNC machined from thick aerospace grade aluminum and finished in a satin and luxuriously rich anodized texture. Large heat-sink radiator fins and hidden handles in the corner structures provide clean lines but maintain practicality.  Large analog VU meters provide information on amplifier power and operation at a glance.

Details like premium Viborg solid copper 5 way binding posts provide yet another tactile sense of luxurious feel when used.  Gold plated premium RCA jacks round off the suite of quality components used throughout.

The heart of the amplifier is a 40W true Class A amp (never operates outside of Class A) designed by Hugh Dean of Aspen Amplifier, PLC (Melbourne). It is based on the Alpha Nirvana amp topology, which provides a beautiful harmonic profile, clean and clear sound with low distortion, slamming bass from low negative feedback circuit, and a background that is absolutely quiet and noise free for the blackest of black notes.  Most of all though, the Alpha Nirvana topology makes your toes want to tap, and your heart race, and your brain feel like it has fallen in love with your music collection all over again.

The the Positive Feedback review where they summed with:

"This is the point where the tech-geek lurking inside my brain takes control, and proclaims the obvious: it's hard to find fault with a pair of amplifiers that are so well-designed, cost so little, and do so very much so very well. And will drive a diverse array of highly-pedigreed and sometimes finicky loudspeakers to reference levels with sound that's both detailed and musically engaging. That I should even complain that the Vera-Links don't play high-resolution files perfectly is completely ludicrous; there's no free lunch, especially in high-end audio, and trust me, $199 is about as close as it gets to free. For the vast majority of the music-listening public, these amazing amps will provide a literal roller-coaster ride of non-stop thrills. Especially if you have a pair of vintage loudspeakers just begging to be employed in a secondary system or for occasional use at parties or other events. The Vera-Fi Audio Vera-Link amplifiers come very highly recommended—and with their crazy low price point, they're a total no-brainer."

Stereotimes summed with:
This pair of Vera-Link Bluetooth amplifiers delivered a lot of enjoyment with their accessible and easy-to-use tech. They work well, connect easily, and sound quite musical. Performance at this affordable introductory price of $199US should bring smiles to many faces. Surf on over to www.verafiaudiollc.com and pick up a pair!
