Amplifiers T-300.2, T-100.2, T-100.3
Two years after manufacture of T-250 power amplifier model it was decided to add a few more amplifier models as well. Moreover, the goal was not only to add, but also to improve the sound quality and technical characteristics significantly. It was not that easy to implement this idea, but as a result T-250 had outstanding sound which was confirmed by numerous playbacks and user comments. It took two years of diligent work to improve the result. The following was modified in T-250 in terms of the circuitry: 1. The printed-circuit board l ...

Oppo Digital UPD-205
After a couple of years after release of Oppo BDP-105D, the model was updated up to UPD-205. It was initially known that the device would be tooled for 4k, and in general it would not bring anything new in the rest. And it turned out that way. After primary inspection of the analog part, my opinion proved true. It remained practically the same. Nominal values of elements were changed a little, but on the whole the circuit design is similar. There are deficiencies of course, as usual. There is space where to apply efforts. The sounding in style ...

Integra DRC-R1 / Onkyo PR-RZ5100
At the end of 2016, the Onkyo Corporation released in the market the AV controller ONKYO PR-RZ5100 and the INTEGRA DRC-R1, analogous to it stuffing. From the point of view of functionality, the new processor differs from the previous version Onkyo PR-SC5530 (Integra DHC-80.6) in the DTS:X support for the audio part and HDR for the video. As for the rest, there are no obvious differences. Visually, inside, the device has been significantly redeveloped, one gets a feeling that the device is quite different. But in reality that is not so. To ...

Oppo Digital BDP-105D
I was constantly coming across online reviews that fortune finally smiled at us – “No other device sounds better, no matter how much it costs”. So, I just had to check whether it’s true. I bought it, tested it. And here’s what I have to say about it. The device is fairly good as a digital source. It’s able to read almost every format of sound and video. User-friendly. Good image. No claims in this respect. But the analog sound was far from being impressive. There’s no arguing that the digital output is good – it really sounds fine, I compared it w ...

Integra DHC-80.6 / Onkyo PR-SC5530
Integra DHC-80.6 is a complete analog of Onkyo PR-SC5530 in terms of circuitry, but quality of assembly is notably higher, plus some program alterations are available. In the market since 2014. Its precursor is Integra DHC-80.3 / Onkyo PR-SC5509 – a unique device in terms of upgrade potential, manufactured since 2011. New features have been introduced since then, like Dolby Atmos system and HDMI 2.0 supporting 4K/60 Hz video. That is why a new processor combining those features was presented. Besides, acoustic system configuration poss ...

Ayon Triton III
Ayon Triton III is actually a typical integrated amplifier blending in with other tube amplifiers. The design is bright, catchy, recherché, but many people find it likeable. That is in fact all I have to say. As regards the sound, the bass is bloated and excessive. Tremble is not quite pure and clear, probably even muffled. The way it creates the stage leaves much to be desired. When we compared it to cheaper analogs of other brands, even much cheaper ones showed better results. But I must admit this amplifier is powerful enough. It will cope with almost an ...

Ayon Audio
I did not describe each Ayon CD player separately. I’d just say that I have sifted through many of them – CD-2, CD-2s, CD-5s, and others. Mostly all top models. Actually, they all are practically the same in terms of circuitry, thus the sound is pretty much alike. This similarity is for the most part attributed to 6n30p output tubes, which give the sound the well-known "roundness". Generally speaking, the hardware is very well assembled, especially in view of its reasonable price. CD-5s has quality Philips CD-PRO2M transport. Digital-to-analog converter microchips - PCM ...

Montana EPS-2
More than once have I installed Montana EPS-2 in various systems, both for music and video. These speakers are worth their price. Solid heavy casing, good filter, firm assembly. Users at forums say that bass is too weak – typical for Montana. This is not true, at least for EPS-2. They do not have an exaggerated bass – it is just smooth. I measured these speakers – the bass is OK within their compass, both by sound and by measurements. Of course, low-frequency speakers of similar size with deeper bass exist, but their sensitivity is notably lower. These very speakers can be called uni ...

Nola Viper 1A loudspeakers
I’ve recently made over loudspeakers of this well-known brand. They sound very specific, the bass is very vigorous, good midrange, bright and ringing treble. Not my cup of tea. Measurements showed that bass is 8-10 dB too high. There is no rear chamber on the midrange speaker, open design, which makes the speakers sensitive to location in the room, and they definitely should not be placed near the back wall. Tweeter had an aluminum dome. Treble exceeded normal values. After disassembly it turned out that the parts inside were loose. Coils were not properly f ...
