Integrated Amplifiers

Big, bold and unashamedly old-school with its silver finish – black is available as an option – polished piano black side panels and large illuminated meters, the £4999 Yamaha A-S3200 is the flagship of the brand's integrated amplifier range, which kicks off with the modest £200 A-S201.

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.

Which are you? The minimalist who wants an integrated valve amp bearing only clearly-labelled inputs, source selector, volume control and speaker terminals? Or do you prefer a 'fully loaded' device with total flexibility? The former is intuitive, and any experienced hi-fi user thinks of such units as virtually 'plug 'n' play'. Germany's 30-year-veteran brand Octave Audio has, in its V70 Class A, an amp that sits between both camps and yet I was compelled to digest its 36-page manual.

It's important to accept how language evolves, particularly when reviewing an amplifier with a name that is a contraction of 'evolution'. PrimaLuna calls its current lineup EVO, as it represents the next step in the advancement of its valve amps, and the 40W-rated £3798 EVO 300 integrated represents the mid-point in a 13-model range.

A'synergy of sophisticated original circuit design and Italian style'. That's the promise of Audia Flight, the company established in 1996 by Massimiliano Marzi and Andrea Nardini. Arguably a 'boutique brand' by virtue of a product line focused almost entirely on amplifiers, the lone standout is a CD player in its entry-level 'FL Three S' range [HFN Sep '07]. We are testing its newest addition here: the FLS 9 stereo integrated which pledges to showcase the brand's audiophile philosophy at a price more manageable – beginning at £5950 – than that of its other high-end creations.

The expression 'hot on the heels' is one thing, but to launch two sets of products seemingly offering similar features at much the same price might be seen as inviting customer confusion. Yes, that's just what Marantz has done, with the SA-12SE/PM-12SE SACD player and amplifier [HFN Nov '20] followed within weeks by the arrival of the 30 Series models – yes, an SACD player and amplifier. Add in the fact that both ranges draw heavily on previous models – to put it charitably – and one might well wonder what exactly is going on.

There's something comforting about a product with a singular focus, and Pass Labs' INT-25 fits that bill. A line-only integrated, it steers clear of the digital inputs, network functionality and onboard phono stage offered by many competitors. Instead, it presents itself simply as a conduit between your source(s) and speakers, combining a FET-based preamp and Class A power amp and nothing else. If that sounds somewhat 'basic', Pass Labs' history and the amplifier's £7200 price tag should suggest it's anything but. As does its mastery of music – but I'm getting ahead of myself…
