Review: Audio Note Meishu Phono 300B Konzertmeister Integrated Amplifier

August 28, 2025 Michael Lavorgna
Pretty damn exquisite. That’s one of the things I have to say about the sound of the Audio Note Konzertmeister—it’s pretty damn exquisite.
HiFi Reviews

Review: Audio Hungary Qualiton 300B Integrated Amplifier

August 14, 2025 Michael Lavorgna
I’ve reviewed my fair share of amplifiers and integrated amplifiers that employ the 300B triode vacuum tube in the output stage.
HiFi Reviews

Review: Wattson Audio Madison Amplifier & Madison LE Streaming DAC

July 31, 2025 Michael Lavorgna
Switzerland’s Wattson Audio makes five products and taking this review into account, I’ve written about four of ’em.
HiFi Reviews

Review: Aesthetix Mimas Integrated Amplifier

July 24, 2025 Michael Lavorgna
In today’s world of overload, that second-by-second flood of data, it’s kind of rare to find a quiet gem.
HiFi Reviews

Review: Octave Audio Jubilee Preamplifier & Jubilee Mono ULTIMATE Monoblock Amplifiers

July 10, 2025 Michael Lavorgna
Power and grace.
HiFi Reviews

Review: JMF Audio PRS 1.5 Preamplifier & HQS 6002 Amplifier

June 12, 2025 Michael Lavorgna
Astonishingly right. After struggling with how best to describe the JMF Audio PRS 1.5 Pre/HQS 6002 pre/power combo, these 2 words seemed to size things up best.
HiFi Reviews

Review: Bel Canto Design Black ACI 600 Integrated Amplifier

May 1, 2025 Michael Lavorgna
I’d like us to think about the Bel Canto Black ACI 600 in architectural terms.
HiFi Reviews

Review: Soulution 331 Integrated Amplifier

February 6, 2025 Michael Lavorgna
Some integrated amplifiers seem to know better than others how to make the speakers they’re driving sound best.
HiFi Reviews

Review: Pathos InPol Heritage MKII Integrated Amplifier

January 30, 2025 Michael Lavorgna
Imagine a luxury ocean liner competing in America’s Cup. And winning.
HiFi Reviews

Review: Luxman L-505Z Integrated Amplifier

January 9, 2025 Michael Lavorgna
Imagine it’s another sleepless night and you’re scrolling through cable stations well into the thousands and you come across a TV Evangelist espousing the dangers of hifi lust.
HiFi Reviews

Review: Atoll SDA300 Signature Streamer / DAC / Integrated Amplifier

December 5, 2024 Michael Lavorgna
There’s something about a Class A/B amp.
HiFi Reviews

Review: Octave Audio V 70 Class A Integrated Amplifier

November 21, 2024 Michael Lavorgna
The Octave Audio V 70 Class A Integrated Amplifier has a lot of great things going for it.
HiFi Reviews

Review: A Cambridge Audio EX Stack | EXN100 Network Player & EXA100 Stereo Integrated Amplifier

November 7, 2024 Michael Lavorgna
I admit that I checked the price of the Cambridge EX stack numerous times throughout the review period.
HiFi Reviews

Review: Fern & Roby Amp No. 2

October 10, 2024 Michael Lavorgna
If you don’t care what something is made from, how it’s made, where it’s made, who made it, what it looks like, how it feels to live with, or how it sounds then you can skip this review.
HiFi Reviews

Review: BorderPatrol S20EXD Parallel Single-Ended Amplifier

September 26, 2024 Michael Lavorgna
When talking ideals in amplification, or any piece of hifi for that matter, my pinnacle is well balanced.
HiFi Reviews

Review: Vinnie Rossi BRAMA Integrated Amplifier

September 5, 2024 Michael Lavorgna
The Vinnie Rossi Brama Integrated Amp slipped, gracefully, onto my list of Favorite Amplifiers soon after it arrived.
HiFi Reviews

Review: Unison Research Unico 90 Integrated Amplifier

August 1, 2024 Michael Lavorgna
I’m tempted to point out that I’ve been very impressed by a number of hybrid integrated amps of late. Nealy enough to be tempted into saying I really like hybrid integrated amplifiers.
HiFi Reviews

Review: A ModWright Stack—LS 99 Balanced Tube Preamp | KWA 99 Monoblocks

June 25, 2024 Michael Lavorgna
Purity and power.
HiFi Reviews

Review: A Naim New Classic Stack—NAC 332 Preamplifier/NPX 300 Power Supply/NAP 250 Power Amplifier

June 18, 2024 Michael Lavorgna
Does anyone really review Naim gear or does Naim gear review us?
HiFi Reviews

Review: Triode Evolution 300 Integrated Amplifier

April 2, 2024 Michael Lavorgna
While I’m no fan of violence, someone needs to take the idea that 300B-based amps are soft and wooly out behind the barn and shoot it.
HiFi Reviews

Review: Audionet HUMBOLDT Integrated Amplifier

March 26, 2024 Michael Lavorgna
When you buy most anything, you’re paying for everything involved in designing, making, packaging, distributing, marketing and selling that thing. You’re certainly not, as some audiophiles appear to think, just paying for some parts.
HiFi Reviews

Review: Thöress EHT MKII Integrated Amplifier

February 15, 2024 Michael Lavorgna
Hybrids are half-loved by some because ideologies can outweigh outcomes. In the case of integrated amplifiers, the outcome I’m most interested in is how power can turn an electrical signal into waves of emotive sound energy as music.
HiFi Reviews

Review: Viva Solista Integrated Amplifier

January 31, 2024 Michael Lavorgna
I can count on one hand the number of integrated amplifiers that stand above and apart from all of the others I’ve had the pleasure of reviewing. Here’s the list:
HiFi Reviews

Review: A Bel Canto e.One Stack | Pre5 Preamplifier / REF501S Stereo Amplifier

January 11, 2024 Michael Lavorgna
I know my way around some Bel Canto, having reviewed their e.One C6i DAC Integrated Amplifier and e.One Stream2 Network Bridge along with the more upscale E1X Integrated Amplifier.
HiFi Reviews

Review: Audio Research I/50 Integrated Amplifier

December 21, 2023 Michael Lavorgna
Tung-Sol introduced the world to the 6550 beam tetrode vacuum tube in 1954, with early production coming out of their Bloomfield, NJ plant. I grew up about 8 miles away and that plant, the Electron Tube Division, remained in operation until I was a teen. […]
HiFi Reviews

Review: Soulution 330 Integrated Amplifier

November 30, 2023 Michael Lavorgna
When it comes to listening to music on the hifi, I’ve been wondering of late if a sense of refinement is innate or learned. In other words, do we know a refined sound or does the gear teach us about it.
HiFi Reviews

Review: Audia Flight FL Three S Integrated Amplifier

October 19, 2023 Michael Lavorgna
The only thing I would change about the Audia Flight FL Three S, if I could change anything, is to have the volume knob stick out a bit more. Other than that, there’s nothing to criticize and everything to like. If not love.
HiFi Reviews

Aurorasound HFSA-01 Review Followup: EQ Curves & 78s

October 9, 2023 Michael Lavorgna
Do you remember the Monkeyhaus? This was the name John DeVore of DeVore Fidelity gave his listening room/office that lives inside his factory in the Brooklyn Navy Yard.
HiFi Reviews

Review: A Stack of Ayre 8s – CX-8 CD Player, KX-8 Preamplifier, VX-8 Power Amplifier

October 5, 2023 Michael Lavorgna
I lived with Ayre’s AX-5 Twenty integrated amplifier for a few years and I’ve reviewed a bunch of Ayre gear so I feel I have a good grip on Ayre’s house sound. I am more than happy to report that the new 8-Series products sing […]
HiFi Reviews

Review: Java Hi-Fi Single Shot Integrated Amplifier

September 28, 2023 Michael Lavorgna
A friend, whose ears and judgement I trust, pointed me to Java HiFi and their GaN FET-based amplifiers. I’d heard the buzz about GaN FETs, more than a murmur, as being able to offer Class D amplification without the sizzle.
HiFi Reviews

Review: Aurorasound HFSA-01 Vacuum Tube Integrated Amplifier

September 7, 2023 Michael Lavorgna
There are times when I forget I’m reviewing, something that happened more than the norm during my time with the lovely Aurorasound HFSA-01.
HiFi Reviews

Review: Octave V 16 Single Ended Integrated/Headphone Amplifier

August 23, 2023 Michael Lavorgna
The Octave V 16 is, as its name says, a single-ended design running a pair of KT120s (or KT150, KT88, or 8550) in triode mode for about 8 Watts of output power per channel, i.e. more than enough power for a few pair of speakers […]
HiFi Reviews

Review: Thrax Enyo Signature Integrated Amplifier

August 3, 2023 Michael Lavorgna
No matter how deep I tried digging into the sound of the Thrax Enyo Signature Integrated Amplifier, music kept smacking me in the face foiling any attempts to listen past the tunes.
HiFi Reviews

Review: A Desktop System – DeVore Fidelity micr/O | Enleum AMP-23R | Weiss DAC204

July 27, 2023 Michael Lavorgna
“Raindrops on roses and whiskers on kittens.”
HiFi Reviews

Review: A Cambridge Edge Stack: Edge NQ Preamp/Network Player & Edge M Monoblock Power Amplifiers

July 6, 2023 Michael Lavorgna
“This magic moment, So different and so new.”
