With the AMG STA-SE, the company has issued a successor to the AMG STA. With this new model, the company sought to narrow the gap between the different sound characteristics of models such as the ST-10 and Evolution STA on the one hand, and the AMG STA on the other

Honestly, I did not think the moment would come that another transistor amplifier would put up serious competition for my treasured CH A1.5, but here we are. Read all about it in the review.

With the Evolution STA, NuPrime has delivered an amplifier that manages to strike a beautiful balance between the strong qualities of the ST-10 and the AMG-STA, while raising the overall performance even further.

The CAT JL5 promises the benefits of pure Triode Mode, combined with very large power reserves and the capability to drive pretty much any loudspeaker, including electrostatics.

In the initial NuPrime AMG review, I have focused mainly on the AMG-STA power amplifier. For this second installment, I have been sent a second AMG-STA power amplifier so that I can use a pair in mono-mode as well as an AMG-PRA analog preamplifier to round off the NuPrime system.

The AMG STA not only addresses all of the ST-10's weaker areas but actually raises the overall quality to such an extent that it comfortably positions itself among high-end competitors that cost multiples upon multiples.

From an American audio brand with a long history, one might expect a stereotypical big and ballsy "American" sound. When talking about transistors this would be maybe something in line with the classic Krell or perhaps McIntosh sound and when talking about tubes, in general, a warm, rich and juicy-liquid sound. But just like modern Audio Research tube amplifiers do not have that kind of sound, neither do the Manley products that I have on visit for review. So, what do they sound like? Read on to find out!

The Monrio mp11's have a luscious sound that is gently sweet and easy-going, airy, highly refined and beguilingly fluid. It's also nothing like what I have become accustomed to hearing from typical Class-D designs, or from Class A/B amplifiers, for that matter.

With each of the two channels powered by its own transformer and extra capacitance, the available power has doubled. But if you ask me, the extra power is not the amplifiers' biggest selling point, rather, it's the increased sound quality across the board.

Machined from solid aluminum, the EPM-700 Mono amplifiers employ hybrid amplification technology using a Class-D Hypex NC500 module with Ncore technology powered by a 1200W switched-mode power supply and a Korg NuTube Triode Valve-based atm-audio input stage.

The Master 2H mono amplifiers amplify the whole truth and nothing but the truth but they combine their truthfulness with a very high level of refinement, fluidity and finesse to make for a performance that is not only spectacularly neutral but also highly natural, rhythmically infectious and hugely involving. Oh, and these amps also double their output with every halving of the impedance. Intrigued yet? You should be!

Fabulously organic and highly seductive and in no way mechanical or electronic, these fully Class-A amplifiers eschew the type of overt control that can lead to the mechanical and clinical presentation that makes so many rivals sound rather uninvolving.

After the initial Bryston review in December 2017 my system changed significantly. Therefore, I thought it prudent to give the amps another run with some very different speakers.

Smooth, fluid, transparent and extremely finely detailed, they relay music with a finesse and lyricism that is rare in generic and in this price class in particular.

Encased in a simple but robust cabinet, the STR series has refreshingly different looks, but these components also distinguish themselves from the masses in terms of sound.

It baffles me why the Bricasti brand does not pop up everywhere, it certainly should. Beautifully sculpted and with immaculate build quality, these components are not inexpensive but in context, they surely are also not extravagantly priced.

This Naiu Laboratory Ella power amplifier is the MK2 version with a new faceplate. While it looks similar to the amp tested in August 2017 on 6moons, this concerns a similar, yet further upgraded version.

A bigger cabinet, a new 1700VA toroidal transformer, new Red Caps, and an improved internal layout not only increase the output rating from 100 to 150 watts into 8 ohms but also make for a huge leap in sound quality.
