Melody MK88 32W KT88 Integrated Tube Amplifier Review

If you had two thousand dollars, and you wanted to be a somewhat responsible audiophile, (is that an oxymoron?) you might want to spend said two grand on a new integrated tube amp. Because right now there are several really amazing integrated tube amplifiers on the market. The Melody MK88, a Class A, KT88 integrated tube amplifier with a clean and no nonsense physical appearance is one of them. Priced at $1995, you’d have enough left over for a couple bottles of Two-Buck-Chuck. To sauce you up as you thoroughly enjoyed your new toy.

Yamaha RX-A3000 Receiver Review

AV receivers are constantly changing, constantly leap-frogging one another in features and capabilities. This year Yamaha announced its Aventage (RX-A) line and, in the process, jumped over a lot of the competition. And not a little jump, more like an Olympic gold medal long jump. Much of that jump is simply in the way of value – we mean the Aventage line in general has build quality and features that seem like it should cost a lot more than it does. The RX-A3000 takes that to the ‘nth’ degree. There are five receivers in the Aventage lineup and the RX-A3000 is the flagship. This 11.2 channel (140wpc x 7) A/V behemoth has endless configuration options, including dual independent subwoofer outputs, full power amp assignability, simultaneous usage of front effect and back channels, full 3D support, and HDMI Standby with switchable inputs even when the receiver is powered down. If you’re ready for the future, the RX-A3000 is ready to serve you in every capacity. It has proven itself to be a worthy and most importantly less costly successor to the venerable RX-Z7.

INEX Innovation Photon A200 Preamp, Photon Monoblock Power Amplifier and Photon Cables Review

Shared Review with Dagogo.com

By Doug Schroeder

It happens in the blink of an eye, in a flash, at the speed of light – the signal is sent, the music plays, and the ears are awash in waves of sound. The soul is stirred, and the mind feels… Free? Empowered? Thrilled?

What is it like to hear sound conveyed at the speed of light? While that may be difficult to report in terms of natural phenomena, I can report what signals sped through optic channels sound like. In this article we will trip the light fantastic, by investigating light-linked, nimble-toed components by INEX Innovation.

We will not be talking about the ability of these popular preamplifiers to transport you to musical bliss or to bring musicians into your listening room. This survey is not about the musical performances of these components and how the bass, midrange, treble, or soundstage is more or less like the “real thing”. Of course, the subject of fidelity to the original source is controversial because any sound recording engineer will tell you that even though they are closer to the actual musical performance than a listener at home will ever be, the sound in their control room, being recorded live, sounds very differently than the sound on the other side of the thick glass window.

Electrocompaniet Prelude System Review

Featured Article from

Electrocompaniet-prelude

Reviewer:  Adam LaBarge

It isn’t often one gets to review a nearly complete system and I jumped at the opportunity to do so, and there is good reason. Reviewing a single component, a speaker, a CD Player, an amplifier, etc. involves certain guess work, and that magic touch it brings to one system might not appear in another. But with a complete system, where the synergy of the components has been worked out by a single manufacturer, basically all that is left is the room and the sound. A complete system takes so many variables out of the equation, narrowing the reviewer/consumer equipment gap, that there is really a good argument to be made for only purchasing a complete system. Especially if you love great music but don’t have the time to test out 20 or 30 different components and all the combinations that could possibly be created out of them. Sometimes easy street is just perfect place to go.

Electrocompaniet EC 4.8 preamplifier Review

Featured Article from

Electrocompaniet-EC-4.8

Reviewer:  Ed Momkus

I’ve been an Electrocompaniet user for many years. I own the fabulous Nemo monoblocks, which drive their namesake B&W Nautilus 800Ds (see my October, 2008 review in Dagogo. I’ve also reviewed the Electrocompaniet EMC 1UP CD player (December, 2009), which despite its age (first introduced in 1999) continues to be one of the most musical players around. Finally, I thought that the Electrocompaniet system, including the new Nordic Tone Model One speakers demonstrated at the 2009 Rocky Mountain Audio Fest, was one of the best sounds of the show. So as you read this review, beware my prejudice: I think that the Electrocompaniet “house sound” is not only easy to listen to, but does a great job in replicating music the way that I hear it live.

A Reference Preamp

Several years ago during my search for a preamp that would be ideal for my system, I auditioned the EC 4.6 preamp. It had all of the positive characteristics of other Electrocompaniet gear, but I thought it fell short on PRAT (pace, rhythm and timing) and did not have the dynamics of better components. The 4.6 was replaced by the 4.7, which I never auditioned, but which reputedly was an audible improvement over the 4.6. Nonetheless, the 4.7 was never positioned as a “reference” product.

The EC 4.8 is different. It is designed as Electrocompaniet’s reference preamp; it does not replace the EC 4.7 – the 4.7 remains in the Electrocompaniet lineup. Rather, the EC 4.8 is a higher model designed for those who demand higher performance. It is designed as a fully-balanced dual mono preamp, with each channel having its own power supply. I suspect that this is one of the design features that makes the EC 4.8 a terrific preamp and a very strong value in its class.

Jeff Rowland Design Group 102 S Amplifier Review

Featured Article from

JRDG-102S

Reviewer: Adam LaBarge

After a few hours of failed starts, I must admit, I’m stumped by how to introduce this review. Most of the time reviewers treat the reader to a little anecdote about this or that, or how the reviewer came upon said amplifier or speakers, or whatever.  Maybe even a luxurious and detailed creation story or snippet of wisdom that most of us won’t have the chance to put into use, but we like it anyways. Really, anything is fine if it gets the reader to continue reading. Are you still reading?
