hfncommendedThe most comprehensively-equipped component of Roksan's Attessa quartet combines phono, line and digital inputs with a BluOS streaming platform and beefy amplifier

So it turns out that network amplifiers built around BluOS streaming technology are like buses. No sooner had we waved goodbye to the £1299 NAD C 700 [HFN Feb '22], then up popped the Attessa Streaming Amplifier from Roksan, a little more expensive at £1495 but cut from the same just-add-speakers cloth. This joins a competitive market alongside not only NAD's device but Bluesound's £850 BluOS-based Powernode, plus other streaming integrateds including Cambridge Audio's Evo 75 and Audiolab's Omnia. Handy for Roksan, then, that it has a lot going for it.

The big beast of the budget audiophile jungle is back with two new models to beef-up its 14-series lineup. Does this affordable CD/amp combination have real teeth?

Something is afoot in the land of hi-fi separates. First we had Musical Fidelity with its M2scd/M2si [HFN Jul '19], then Cambridge Audio's AXC35/AXA35 [HFN Sep '19] and now Rotel has launched its own affordable amplifier and CD player pairing, in the form of the £429 CD11 and £599 A11.

hfnoutstandingWithout any sense of irony, the man most identified with rival brand Marantz for 40 years is posthumously recognised for his work in 'tweaking' Rotel's budget CD and amp

Synchronicity is a strange thing: for whatever reason of scheduling, I found myself embarking on this review a year to the day since the passing of audio legend Ken Ishiwata. The anniversary was marked by his daughter with a YouTube video of some joyously retro Latin music performed by an all-Japanese vocal group. 'Instead of making this a very sad day,' she wrote, 'we would like to share one of his favourite songs with you. He used to play this all the time, it brings back lovely memories and a smile upon our faces'.

hfnoutstandingThe 'entry-level' model in a range of two new, fully-featured Michi integrateds, the X3 is a distillation of Rotel's award-winning pre/power design with astonishing power on tap

This amplifier is substantial, beautifully designed and finished, powerful (rated at 350W/4ohm) and hefty, at getting on for 30kg – and yet it's the base model of two integrated amplifiers recently added to Rotel's revived Michi range. Following on the heels of the EISA Award-winning P5/S5 pre/power amplifiers [HFN May '20] and the M8 monoblocks [HFN Oct '20], the X3 and bigger X5 all-in-one amplifiers are the next stage in the expansion of this lineup. The £6300 X5 claims 600W/4ohm and while the £4300 X3 model may be 'lower powered' it's still able to deliver quite a wallop when required, offering a very impressive bang for your buck.

hfncommendedTop integrated in Rotel's flagship Michi series leverages much of the P5 preamp and S5 power amp technology to realise a taller, heavier amp that aims to upstage the X3

Expect the unexpected: it will be the first lesson in the book if I ever get round to writing Hi-Fi Reviewing For Dummies. You see, just because something seems like something else, it doesn't follow that it is... Too many times I've stumbled across a speaker sitting in the middle of a range, and apparently using the same recipe of drive-units, that turns out to be a complete outlier – for good or bad – in the way it plays music. The same happens with amplifiers, too. So, just because one model seems little more than a bigger version of another, don't expect it to have the same kind of balance of qualities, only 'more so'.

hfnoutstandingLaunched as part of Rotel's 60th anniversary celebrations, this is the latest version of the brand's flagship 'big integrated' amp – and there's rather more to it than meets the eye

Rotel's larger integrated amplifiers have always provided an attractive waypoint between the compact designs of hi-fi's affordable end and the monster amps of the high-end, offering plenty of power, an extensive feature-set and an entirely convincing performance. The new RA-1592MKII, selling for £2295 in black or silver finishes and claiming a 200W output, is no exception.

After 45 years in business Rotel has every right to do things its own way. The new RSX-1560 gloriously raises its middle knob to the herd, eschewing games of specification trumps and symphony-length features lists. It is also thoroughly gorgeous to behold, and you can’t say that about many of today’s AV receivers. The clean fascia, sturdy case and chunky polished corner pieces give it high-end panache while the rear panel is a cornucopia of beautifully crafted gold plated terminals.

The TA-1120 stereo amplifier was a step-ahead design which combined power, quality, reliability and compactness in a way that had not been seen before, but which in a few years would become ubiquitous across the ranges of Japan’s major hi-fi brands. In 1968 the original TA-1120 was replaced by the TA-1120A, as tested here, the addition of a headphone socket and the removal of a ‘safety’ indicator light being the only obvious external clues as to which model is which. Revisions were also made to the preamplifier circuit. The main selector lever gives a choice of phono 1 (MM) or tuner, along with a central position that selects a rotary control giving four further options, eg, mic, tape head, second MM turntable and line-level auxiliary input, which can be used to connect a CD player.

An innovative amplifier featuring sophisticated adjustable impedance matching. From the outside at least, what we have here is an integrated amp seemingly conventional in most respects, though its dimensions are just 440x80x410mm (whd) meaning it takes up no more shelf space than would a small turntable.

hfncommendedThis famous French brand was launched in 1956 – the very same year as Hi-Fi News – and continues to cut a very distinctive path. We test its latest tube/hybrid integrated

When your brand has been around for over 60 years, designing a new integrated amplifier becomes a matter of balance. You need to weigh up the company's rich heritage with electronics that compete with the best new kids on the block. Perhaps something to caress the ears with valve warmth and character, combined with the grunt of a transistor output to drive even the most reticent of speakers? Enter the Supravox Vouvray.

hfncommendedHaving nailed the whole 'one box system with built-in speakers' category, T+A now shifts tack to a 'just add speakers' unit. It's on-trend, and with substance to match the style

Are we downsizing, simplifying, or just looking for more from less? Whatever the reasons, it seems the one-box system, to which one only needs add some speakers, is in the ascendant. There's no denying a movement is growing, with everything from 'more integrated' amps complete with onboard streaming through to complete systems such as the NAD M10/M33 [HFN Jun '19 & Aug '20], Naim's Uniti range [HFN Mar '11 & Nov '17] – which was in the vanguard of this trend back in 2009 – and the recently-announced Cambridge Audio Evo models [News, HFN Jun '21].

hfncommendedAs T+A's midrange E series is reinforced by a new amplifier, based on the PA 1000 E but equipped with BT and a USB DAC, we ask 'is this now the stereotype for modern amps?'

As the latest in a long line of amplifiers from the German brand, T+A's PA 1100 E integrated is also one of the more innovative and comprehensive in its scope. The company (T+A stands for 'Theory and Application') has been manufacturing audio equipment since 1978 and prides itself on both its deep technical capability and in-house manufacturing. However, despite this heritage, the PA 1100 E is only the first of its amplifiers to include an onboard DAC – something very many competing brands have been doing for years.

Germany’s T+A has spent the last couple of years developing a completely new range of all-solid-state electronics: its ‘HV Series’. Built into an all-aluminium case, the PA 3000 HV amplifier’s individual sub-assemblies are screened in separate chambers. An upper compartment houses the preamplifier and voltage amplifier stages, while the electronic control processor and circuitry for driving the display screen – fed by a separate power supply arrangement – sits in a recess machined out of the 40mm-thick aluminium front panel. A 10mm-thick dividing wall shields the top section from the left/right current amplifier stages and the unit’s massive power supply is in a lower compartment.

hfncommendedThe latest addition to the Italian manufacturer's range is said to be a ground-up design to make the most of its hybrid – valve preamp, solid-state power amp – configuration

Based in Treviso, Italy, Unison Research has long specialised in making very traditional looking tube amps with polished wooden chassis and rows of glowing bottles on display. At the same time its Unico series has adopted a more mainstream aesthetic and includes valve-based amplifiers that, well, don't really seem like valve amplifiers. Despite an outward appearance suggesting a completely conventional integrated amp, the Due – which sells for £2500 in standard silver with black available at a £100 premium – is very definitely a valve amp, or at least half of one.

hfnoutstandingHot on the heels of VAC's flagship separates stack on our March '21 cover comes the more affordable derivative, the integrated VAC Sigma 170i – is it a true Mini-Me?

If I wasn't averse to tattoos, I'd have one that says, 'Always Read The Owner's Manual First'. I spent so much time trying to illuminate the VAC Sigma 170i's iQ warning lights that I was wondering if the review sample was a dud. Doh: in this application, the £10,000 single-chassis alternative to the Signature stack [HFN Mar '21], they don't light up at switch-on. Here they only work when something is amiss. Blast it! I never did see them in action.
