No crossover distortion in the output stage leads to unrivaled purity nearly immeasurable distortion and the trace amounts are 2nd harmonic.

Gains a vistavision-like soundstage and sunshine transparency from its state-of-the-art current-feedback open-loop dual-voltage transimpedence preamplifer section that also features an exceptional MM phono stage. Timeless styling and a perfect Titanium finish; feels like a real tank, excellent dial ergonomics, and those heatsinks are beautifully curved for pain-free handling.

The Sugden Masterclass IA-4 produces a huge, crystal clear sonic picture. Completely grain-free, gargantuan soundstage, blistering speed, forceful bass, endless treble extension, and a rich and kaleidoscopic midband. Sugden has been hand-crafting Class A integrateds in West Yorkshire since and they have their game down.

Weighing a substantial 20 kilos the IA-4 has a purposeful look and impressive build quality. Plenty of input and output facilities are on offer including a high quality phono stage. The class A power output circuit has been upgraded from the A21 series with a larger power supply and improved smoothing and output capacitors. Gold plated circuit boards, full relay switching and a precision input selector switch offer further detailing.

The pre-amplifier section of the IA-4 is a bespoke design with flawless clarity and detail. The most noticeable feature is the ability to create a large performance with depth and height on any type of music. Includes all original packaging, remote, and accessories. Excellent amp! Good luck with the sale. It is genuinely stunning in its performance and I'm happy to help others enjoy it! Also, what a thoughtful message; thank you!

If I didn't have too much gear already, I would have pulled the trigger. My pleasure. Looks in perfect shape. Someone will love it. Price reduction: for an even better value. I honestly can not believe this one has not sold yet. Best of luck! Absolutely wonderful sound. Stunning too through my Devore 93s and Studio Electric M4s - an all around beautiful, crystalline, natural sound!

I so hope someone gets to enjoy it soon. Siltech Jr. Member Posts: Thank you. Hi Ron, it sold for a higher offer.

As you may remember, Piega 5. Knowing that I am a big fan of good Class A amplifiers, jack-fi. This amplifier only has 33W into 8 ohms, but they are full Class A. What I am trying to say is that an Class A amplifier capable of 33W is quite powerful. The first thing I noticed was a relaxed and musical sound signature. Actually it was brought forward in a natural and textured manner.

Sugden Audio Masterclass LA-4 Class ‘A’ Line Pre-Amplifier


A headphone amp and remote handset are included in the base price. With line-level sources, Mikey noted "ultra-low" noise, "very high" transparency, "very good" dynamic expression, and "impressive" frequency extension and balance. Its active output buffer is based on Ayre's "diamond circuit" arrangement of bipolar transistors. And its AyreLock approach to voltage regulation creates, in essence, a push-pull power supply capable of turning on a dime in response to the demand dictated by the music signal. All of this is packaged in a non-huge aluminum enclosure described by AD as "tidy and evidently well laid out. Like other Benchmark equipment he has tested, the affordable LA-4 challenged the resolution of JA's test instruments, with "superb" channel separation, "extremely low noise, and virtually no power-supply-related spuriae.

For just over half a century, for almost as long as there have been transistor amplifiers in fact, there has been Sugden. The Sapphire range is the latest from a brand that cycles its products about once in a generation.

Sugden Audio are masters of their craft. Since , they have been producing amplifiers, digital processors and loudspeakers with exceptional musical qualities. Amplifiers which are hailed as classics and which are sought after even to this day. The Sugden signature sound gives you the rich bodied sound of valve amplifiers without the related issues. The company continues to hand-build products with each individual unit being the responsibility of one technician. This may appear indulgent in an age of automation and mass production, but it can be justified by the quality standards, which are the payback of a satisfied workforce. Sugden production methods are the antithesis of robotic mass production and the maelstrom of that working environment.

The electronic circuitry of the LA-4 has been developed to offer the best possible sonic performance without compromise including the use of specially selected transistors and capacitors to provide the best signal preservation.
