Pass Labs X250.5 Stereo Power Amplifier

Wyred 4 Sound ST-1000 Stereo Power Amplifier

The high-end is dead! Long live the high-end! A paradigm shift is upon us now. In the Wyred 4 Sound ST-1000 stereo amplifier, we have a maturing technology that absolutely changes the performance-to-price expectation for solid-state amplifiers in the $2,000

JL Audio Fathom f112 Subwoofers

Balanced Audio Technology VK-220 & VK-250SE Power Amplifiers

These two amplifiers are children from the same BAT family and have similar BAT sound qualities. The 125W per channel VK-220 ($3000) and the 150W VK-250SE ($7000) employ mosfets in their output stages. Both amplifiers are fully balanced designs and

Halcro MC20 Power Amplifier

NAD C315BEE Integrated Amplifier

Paul Basinski I'm neither a mad dog nor an Englishman, and yes it has been hotter than blazes in downstate New York this summer. That, and not an abdication of reason, explains why I have swapped out my Cary SLI

Benz-Micro LP Moving Coil Phono Cartridge and Tri-Planar VII Tonearm

Good old Benz-Micro cartridges. They have been around for so long that we take them for granted. As Rodney Dangerfield might have said, they get no respect. After living with the Benz “Ebony” LP moving coil phono cartridge for more

Cary Audio Design SLI 80 and Bel Canto e.One S300i Integrated Amplifiers

Paul Basinski Audio friends, you have heard it before and here it is again: for good sound from your home music system, the synergy between amplifier and speaker is critical. In my experience, if you get a correct match between

How do you improve on perfection? There is no Darwinian natural selection at work for manufactured products that enable them to evolve over time, making them better suited to the environment. If you are an expert marksman, hitting the bulls-eye

Five Balanced Interconnect Cables

I was just sitting there listening to music. I was enjoying the apparent sound stage created between the loudspeakers and wondered how my system would sound without the equipment rack sitting between the speakers and then the trouble began. My

Harbeth Monitor 30 “Rendezvous” Special Edition Loudspeaker

I debated for a long time whether or not to write this review for two reasons: 1. This speaker has "good buzz" and I wondered if mine would be the lone voice in the forest of opinions. This dichotomy would

Benchmark DAC1 D/A Converter

Several of you have sent emails to me with your comments about my preference for analog sources. These comments range from “Right on, Dude. You got it right!” to “Your reviews are worthless without including digital as a source”. There

Koetsu Jade Platinum Moving Coil Phono Cartridge – MINI REVIEW*

The Koetsu Jade Platinum moving coil phono cartridge has always been a dream component for me. For many years, I would look at ads that offered the cartridge and pay particular attention to newsgroup threads that mentioned it. I have

Audio Research LS22 Preamplifier

SOTA Cosmos Series IV Vacuum Turntable

Benz Micro MC20 E2 Moving Coil Phono Cartridge

Paul Basinski Need a little shot of Vitamin E for a turntable that's become somewhat stale and dull? Then let me recommend an inexpensive MC cartridge from the Swiss company Benz Micro. It's the Benz MC20 E2. At a retail

Zyx UNIverse MC Phono Cartridge

Reviews of phonograph cartridges can be pretty darn worthless. Irrelevant. Reviews can put a cartridge into some kind of comparative framework where you understand that Cartridge A does this or that, more or less, better or worse, than Cartridge B.

ModWright SWLP 9.0SE Preamplifier

I had a good idea last year. I may have had another good idea in 2006 than the one, but I don’t remember it. The good idea was about music listeners, like you and me. In my review of the PS

Electronic Visionary Systems 500M Power Amplifiers

VPI Scoutmaster Turntable with JMW-9 Signature Tonearm

Paul Basinski The VPI Scoutmaster Signature turntable is a veritable beast. Weighing in at 48 pounds without hernia-inducing options like the outer ring clamp, Gingko dustcover, Delrin clamp, or upgraded platter, this is one solid machine. That was the first impression that

Spendor S5e Loudspeakers

Small and lightweight and good looking. These are the first impressions I had when unpacking and setting up the 2 ½ way Spendors. They were smaller in person than I expected them to be, measuring just 31.1 x 6.5 x

EAR 88PB Phonograph Preamplifier

I was becoming complacent auditioning phono preamplifiers. It was as if I was standing in a long line for my turn on one of the good rides at Disneyland. If I was tolerant and patient, I would eventually be rewarded

Denon DL 103R Moving Coil Phono Cartridge

By Paul Basinski The subject of this review, the Denon DL 103R is about as elusive as the rare spotted owl. No sooner do you discover one of these low output moving coil cartridges new or used on the Web

Rogue Audio Metis Preamplifier

Grado Sonata and Benz-Micro Glider Phono Cartridges

First, understand that these are two very good, but very different sounding cartridges. They are perhaps a peerless pair of the best performers in the crowded sub-$1,000 realm. Secondly, let me say that most people will not like both of

Response Audio Bella EXtreme 100 Power Amplifiers

I’m speechless. Or wordless. I had quite a lot to say about the new Response Audio Bella EXtreme 100 mono tube amplifiers during the first 400 hours of use while the Teflon® capacitors and other parts were slowly breaking in.

PS Audio GCC-500 Control Amplifier and Underwood HiFi-modified GCC-250 Control Amplifier

Slinkylinks Interconnect & Speaker Cables

Gallo Reference 3.1 Loudspeaker

Loudspeakers are not natural. Go outside and listen to a bird, or hear a piano, a French horn, a guitar, or even a drum. This is natural sound. Now listen to those same sounds on a typical loudspeaker where they

Audio Research PH5 Phono Preamplifier

This won’t take long. I installed the Audio Research PH5 phono preamplifier and let it warm up for 24 hours before listening. It had been used for several months and was well broken-in before I received it. One of the

DIY “Jensen 44” MC Step-up Transformer

Several years ago, I borrowed an Air Tight ATH-1 moving coil step up transformer and it changed my life. Well, maybe it was not a life-altering experience, but in audio terms, the audition was significant. The Air Tight sounded exceptional,

PS Audio GCPH Phono Preamplifier

Ortofon Jubilee, Kontrapunkt A & B Phono Cartridges

PS Audio xStream Resolution Reference and Transcendent Interconnect Cables

Things are getting very interesting in the high-end audio arena, and you and I are the beneficiaries. We have seen new technologies introduced over the years with their high initial prices. We have watched as these state-of-the-art parts and manufacturing processes become

Audioquest LeoPard Phono Cable

We do not have dozens of phono cables available from which to choose, as we do interconnect cables. It seems that only a few of the top manufacturers offer cables specifically designed and configured for the critical tonearm-to-phono preamplifier connection.

“DIY Hydra” Power Conditioner

PS Audio Ultimate Outlet vs. Shunyata Hydra 2 Power Conditioners

I am always reticent about recommending power products such as power cords and power conditioners. Their effects in my own environment vary greatly with different equipment and even with the time of day. Many components’ basic characters can change dramatically

This is a preliminary review (final thoughts below). The Cary 500MB power amplifier is such a superior music making audio product that I feel compelled to post an early report on my experiences with these wonderful amplifiers. The review could

Placette Passive Line Stage Preamplifier

Finally...sigh...a component that does exactly what the manufacturer says it does and nothing more. This is the first component in my experience that has so little identifiable character as to be, in the most exact meaning of the word, transparent. But

Capacitors: Sonic Craft Sonicap Gen. 1 vs. VH Audio V-Cap OIMP vs. RELCAP Multicap vs. Mundorf Silver/Oil

Passive Preamplifiers

Here is a basic schematic for an excellent passive 'preamp': Notes: You can insert a source selector between the input and the 1k resistor. Speaking about the 1k resistor - it should be a Caddock or Vishay. Weak link theory applies. The

Quicksilver V4 Power Amplifiers

This is not an easy review to write. For several months, the Quicksilver V4 amplifiers have been the primary amplifiers in my ever-changing audio system. I have connected them to four different preamplifiers and four different speakers, and numerous cables

PS Audio xStream Resolution Reference Speaker Cables

Magnepan 10.1 Speaker

The Magnepan 10.1 speakers arrived and quickly proved 3 things: 1. A planar loudspeaker can present an incredibly realistic soundstage that is almost completely unknown using cone-type speakers. The 10.1 was chosen because it is a 2-way design, so there is

Balanced Audio Technology VK-31SE Preamplifier

There is no control design in the world of high-end audio that is better than the user interface of products by Balanced Audio Technology. The remote control of volume – even when the output is muted – is a great

Balanced Audio Technology VK-300xSE Integrated Amplifier

Integration: There is something to be said for putting the preamplifier and power amplifier in one box. There are two main advantages to combining these components: technical and cost. An integrated amplifier allows the engineer to design the preamplifier output

Conrad Johnson Premier 15 with Jensen MC Transformers

These are the first images of Jensen JT-347-AXT MC transformers installed in a Conrad Johnson Premier 15 Series 2 phono preamplifier. These are wired in 1:12 gain, for 21 dB. With the transformers installed, the total gain of the Premier

BAT VK-P5 and VK-P20 Phono Preamplifiers

The Balanced Audio Technology VK-P5 phono preamplifier is a well built, reliable, and easy to use stand-alone phono stage. It was a sonic disappointment. It is not a bad sounding component, but it is clearly one made to sell for

Conrad Johnson Premier 15 Series 2 Phono Preamplifier

Think of the cardboard drink carrier that you get at the counter of a fast food restaurant when you order several drinks. The carrier doesn’t interact with the drinks in any way. The carrier doesn’t make the drinks colder or

Shelter 90x Moving Coil Cartridge

What is the difference between an ordinary hamburger and a great hamburger? The meat? The bun? The seasonings? Maybe it’s the cook. It is all of these and more. I say that because if you give the same ingredients to

Sonic Frontiers Phono 1SE Phono Preamplifier

This was a challenging review to write. Not for some of the reasons you might imagine: faulty equipment – none!, system changes – frequent but not the issue; available time to listen to the amplifier – always in too-short supply;

Antique Sound Labs 1006-845(DT) Power Amplifiers

Dynamic…extended...powerful. These are the initial impressions when I first heard the Antique Sound Labs 1006-845(DT) mono power amplifiers. Since this was my first exposure to the 845 tube, I didn’t know quite what to expect. Any expectations I had going
