The high-pass crossover function allows you to filter the output of one of each amplifier pair – there are two amplifier modules per channel in the RA180 – above 600Hz-6kHz. You might choose to use this function to limit the bandwidth of the amplifier feeding the treble arm of a bi-amped speaker, for example, or set it to the top 6kHz filter before driving a supertweeter.

A typical stereo amplifier features four loudspeaker terminals. The RA180? Sixteen, which is astonishing even if you consider the A/B speaker option (note that’s an ‘either’, not an ‘and’, option, as you cannot enable the A and B pair at the same time). As previously mentioned, there are not two but four identical amplifier modules in the RA180 for a claimed total of 4x200W. But you’ll only use the four together when utilising one of its specialised speaker modes, either to bi-amp a pair of speakers (two amplifiers per channel) or bridging each pair into a higher-powered stereo configuration, where the claimed output becomes a whopping 2x400W.

There are a number of areas that we feel are open to criticism. The most obvious of these is its inability to portray dynamic contrasts convincingly. There isn’t the requisite level of dynamic expression we would expect from a product of this price. The result is that this amplifier sounds restrained, almost as if it is gently compressing the music signal, losing excitement in the process. Want to listen to Beethoven’s Fifth or Help! by the Beatles with some of the energy taken out? No, neither do we.

A side effect of this is that regardless of the partnering speakers, we find ourselves constantly playing with the volume level. It’s a struggle to find the point where the music displays the required sense of life without pushing the volume level too high for comfortable listening. This is an amplifier with clearly defined upper limits. Push it hard and things become harsh and edgy very quickly.

Combine these shortcomings with relatively poor rhythmic drive and the inability to communicate changes in musical momentum well, and it’s no surprise to find that our musical enjoyment is diluted.

My ears were trained years ago, late at night, in dark recording studios. I listened to thousands of hours of music, through the iconic Yamaha NS-10 studio monitors. The NS-10s were legendary in their transparency. No musical sin could hide from these speakers. None. If there was a problem, the NS-10 would reveal it. The Pass Labs X260.8 monoblock amplifiers remind me of these speakers.

If you love power, grace, transparency, and (if you move your equipment around a lot) occasional back pain; I highly recommend you demo a pair of the Pass Labs X260.8 monoblock amplifiers or any of the Pass Labs .8 series amplifiers. You will not be disappointed. Highly recommended!

Compared to many other silver disc players, CDs on the SACD 30n had a nice depth and weight that made them sound more like SACDs. SACDs sounded better still – solid, weighty, and clean, with bite and clarity, plus a nice unexaggerated naturalness.

Playing Copland Orchestral works Vol 1 SACD [Chandos CHSA 5164] the bass drum on ‘Fanfare for the Common Man’ had truly awesome heft and depth – real floor-shaking bass, but only if your speakers are capable of reproducing low frequencies below 25Hz.

The LSA VT-70 Integrated Amplifier

With internet pundits claiming high end audio is going under on nearly a daily basis, this is precisely the kind of product to get more people interested in a decent music system that might have thought they couldn’t afford it. Honestly, we need a few more benchmarks like this.

The LSA VT70 is the perfect amp at the perfect price, whether you’re investigating high performance audio for the first time, taking your first spin with a tube amplifier, or perhaps looking for a great second system. It’s musical satisfying, aesthetically pleasing, and gets the job done. Highly recommended.

Enter Frank Zappa. ‘Peaches En Regalia’ from The Mothers 1971 [Zappa ZR20038] provided an alternative in that it was recorded at the Fillmore East, so it has a live rather than studio acoustic, while the music is loaded with cacophonous notes. Though far removed from the highly disciplined, note-perfect Sinatra performances, the Zappa recordings share a demand for the convincing recreation of space. Zappa’s guitar floated just right of centre, while the frantic percussion dominated the left. What stood out among the NYC 200i’s primary strengths, though, was the incredible stage depth.

I long ago stopped being a soundstage fetishist, cognisant of how many mono recordings I played, but the antics of Zappa and Co throughout the concert involved enough left-right movement to remind me of early stereo LPs and tapes. What this did for the listening experience, as a challenge for the NYC 200i’s abilities, was to spread out the audience noises – even in stereo, not 5.1 surround – with an effect that reminded me of early Cinerama. This wasn’t a wide but flat, 2D soundstage; I’ve already praised its depth. Rather, with the Fillmore recordings, it reproduced an arc, the sound extending beyond the speakers’ edges.

Why is that so important? Just as the vivid, lifelike warmth and textures of the Frank Sinatra recordings added to the sense of ‘being there’, so did the NYC 200i’s near-enveloping soundstage increase a sense of involvement. No, I wasn’t present 51 years ago when the Mothers performed at the Fillmore. But, hot damn! This amplifier did a remarkable job of transporting me there.
