a solid-state amp sounds tuby is rolled off highs and anemic bottom end, with high levels of THD added in to boot), what the NFB-1 AMP does sound like is what an amplifier should sound like, which is nothing, no coloration, or more to the point, like music, completely transparent.

For anyone looking for a top-notch headphone amplifier that works well with all types of headphone and music or an inexpensive preamp with a built-in headphone amp, then Audio-gd has your ticket and it is called the NFB-1 AMP.

It’s a taut and precise presentation; one that edges towards the lean side of neutral without going as far as to be criticised for being thin or lacking in tonal colour. It’s this balance that allows the amplifier to sound so nimble for something so muscular.

Stereo imaging is terrific. The Progression paints a broad and expansive soundstage and populates it with crisply focused instruments. The orchestra is convincingly layered and there’s a pleasing impression of depth. This positional grip isn’t compromised when the music gets difficult either.Advertisementhttps://9a57bdb350320d1455158b06de8bb766.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

We switch to Massive Attack’s Heligoland and are floored by the D’Agostino’s low frequencies. They’re superbly defined, beautifully layered and punched out with rare agility. There’s plenty of muscle and authority of course, but that’s to be expected given the power output on offer. What surprises – and impresses – us the most, though, is the Progression’s articulate nature.

Technics SU-G700 Integrated Amplifier

The SU-G700 has no negatives, and we haven’t even discussed the beautiful enclosure and attention to detail that goes along with this product. From the thick front panel, to the delicately lit power meters and even the high quality of the silk screening on the meters is in five-figure product execution range. If you are a build/style junkie, you’ll freak out by the level of overall quality present here. This is one beautiful piece of hifi gear – and it’s also available in black.

What the Technics SU-G700 does is provide you with a top-notch anchor for a great music system at an incredibly affordable price. It sounds great, looks fantastic, and offers an intuitive user interface too. Good as the remote is, the quality and feel of the controls just beg you to walk up to it, give the volume control a bit of a spin, and watch those power output meters come to life. Pairing it up with the SL-G700 and the speakers of your choice make for an incredibly high value proposition.

Although my system is multichannel, there is no processor or preamplifier. The output of the DACs drives the power amps directly via balanced connections. I used the NAD’s XLR inputs in both stereo and bridged modes. When playing two-channel music, I used fixed gain. Fixed gain in stereo mode (28.6dB) also worked when playing multichannel with one C 298 powering the front L/R speakers. However, to use a pair of bridged C 298 amps, my options were to use fixed gain and adjust the channel balance in JRiver or the DAC or to use variable gain to match the other channels. The character of the amp remained constant across all these permutations

It is time to conclude, dear reader; and many thanks for your interest. I know Steve Ginsberg and TAA’s Head of Electrical Engineering, Adam Thomaes, would agree with George Polychronidis of Moon River Audio—forgive me for quoting the competition—when he states that in the audio industry there is a misunderstanding about power. ‘Power is always measured by a constant, stable frequency in the lab—a single continuous sinewave without alterations of the level in time—when the major question is how much power an amplifier can deliver instantly, not constantly. Measuring with a stable frequency doesn’t tell you much about how an amplifier will handle musical dynamics, follow precisely music’s chaotic and complex transients, and drive the speaker.’

Starting with the basics, the Evo is extremely quiet. I am regularly surprised about how many high end amps have transformer buzz or hum. Quite frankly, it drives me bonkers. A few years ago, I had to obtain two Emotiva CMX-2 with their Precision Common Mode AC Line Filter With DC Offset Eliminator in order to review $30,000 monoblocks that buzzed loudly when plugged directly into the wall. Given the vagaries of the AC supply in many places, I would expect a designer to anticipate what needs to be done to prevent such issues in a home listening environment. Similarly, I am bothered to no end by thumps, clicks and thuds that occur during turn on, turn off, and anything in between.There are absolutely no such irritating issues with the Evo. The build quality, attention to detail, and the obvious expertise that went into this amp are impeccable in every respect.
