The very special Technics SU-G700 Amplifier

There are always alternative ways to skin a cat. The ‘chat noir’ of hi fi has always been ‘coherence’ – it is a creature occasionally alluded to, but mainly ignored. Which is a shame, because time coherence is as fundamental part of music reproduction as dynamic range. It’s not talked about because it is filed under too difficult. None the less, all the most musical speakers take into account phase coherence. Technics understand this, and with their new SU-G700 amplifier you get a time coherence ‘get out of jail free’ card, in the form of LAPC.

AND IT WORKS, MAKING ALMOST ANY SPEAKER TIME COHERENT

LAPC (Load Adaptive Phase Calibration)

Speaker impedance changes with each frequency and a power amplifier is required to drive speakers without being affected by the speaker’s characteristics. However, conventional digital amplifiers are connected to speakers through a low-pass filter at the output stage, so they are even more strongly affected by the speaker impedance characteristics. Also, although the amplitude characteristics of conventional amplifiers due to negative feedback were improved, the phase characteristics could not be enhanced. We thus developed a speaker impedance adaptive optimisation algorithm that performs correction to the ideal impulse response through digital signal processing by measuring the frequency amplitude-phase characteristics of the amplifier with the speakers connected. This new technique enables flattening the frequency characteristics of amplitude and phase, which had previously not been achieved by amplifiers, as well as delivering a sound with rich spatial expression.

Rega Planar 6 & Neo PS

The Planar 6 is built around the huge success of the RP8 and RP10 turntables. It is the first new Rega turntable to be constructed with an ultra lightweight Tancast 8 polyurethane foam core plinth (a material developed for the aerospace industry). This material is sandwiched between a new HPL (high pressure laminate). HPL is exceptionally thin whilst extremely rigid and is presented in a stunning Polaris matt grey finished with high gloss polymer black edge trim.

The Planar 6 now benefits from a single piece, machined aluminum sub-platter, a new 24v motor hand tuned and matched to its own NEO power supply and custom drive pulley fitted with our upgrade drive belt as standard.

The Neo PSU uses the RP10 DSP (digital signal processing) generator built upon a high stability crystal. The DSP generator will divide the accurate signal from the crystal to the exact frequency required to turn the platter at the selected speed. The DSP generator will also produce a near perfect sinusoidal waveform to drive the motor. This, along with an efficient drive amplifier, generates a 24V AC balanced signal of less than 0.15% distortion, which is completely un-affected by any changes in the mains/line voltage and conditions. This then drives the turntables anti-vibration circuit, which is situated beneath the turntable.

Key Features:

  • NEO power supply.
  • Super lightweight foam core plinth.
  • Plinth laminate: New Polaris HPL (high pressure laminate). Non-marking matt finish scratch resistant high rigidity skin.
  • Available in one finish ‘Polaris Grey’ matt finish with high gloss black polymer edge trim.
  • Upgrade white drive belt fitted as standard.
  • Custom dual layer smoked / clear float glass platter.
  • Single piece aluminium sub platter.
  • Custom machined high precision drive pulley.
  • Patent pending, ultra-low friction central brass hub.
  • Rega’s double brace technology, with integral custom matched aluminium tonearm and hub pillars to ensure maximum rigidity and accuracy.
  • RB330 handmade precision tonearm with custom stainless weight.
  • New high spec Rega 24v low noise synchronous motor – each motor matched by hand to its own NEO PSU ensuring optimum anti-vibration control.
  • New smoked dust cover.
  • New aluminium foot trims and Planar style feet.
  • Available with Ania MC cartridge factory fitted / Discount available when factory fitted.

Edwards Audio IA1 Integrated Amplifier £399

A British made amplifier for less than £400! £450 with optional phono stage.

The Edwards Audio Apprentice IA1 Integrated Amplifier is an all new design from the ground up.

The intention was to try to build the best and least expensive British made amplifier on the market, just to prove that we can still do it. The result is the impressive Edwards Audio series of integrated amplifiers, which we feel is a very attractive product with our customary top level of sonic performance.

The main design is a spin off from its bigger brothers, with some lessons learnt along the way. It is based around an all new class AB, Bi-polar, Darlington configured output stage using Sanken devices, coupled with a differential front end and buffered voltage stage. The main PSU consists of a custom wound toroidal transformer with 20,000uF of smoothing. The active pre-amp section uses a Soundwell volume control and features relay input switching. So, there are no compromises on the parts!

The IA model design brief was to produce a ‘hair-shirt’ all out performance product that anyone could afford, which especially in these tough economic times we believe is an important consideration, so the only concession to modernism has been the elimination of remote volume. The IA1-R has remote volume if you can’t live without it!

The elegant ‘half width’ case size with RED LED backlit display allows the amplifier not to be imposing in the domestic environment even with  its flexible input arrangement:  you have 1 x line level on 3.5mm stereo jack and 4 x line level inputs on RCA, one of which is labelled OPTION, for use with the optional moving magnet RIAA input stage.

The PCB’s are all surface mounted using Vishay mini melf 1% resistors – not the usual thin film type which sound inferior. The capacitors, no less than Panasonic FM series and larger components are all hand placed and hand soldered as flow soldering has a negative impact on sound quality.

So where have we been able to make the savings? Well the answer is simple, by investing over many years in buildings and machines we have very low overheads and consequently a low cost of production. This is enhanced by some efficient design techniques that enable us to produce a complete tested amplifier in less than an hour, most of which is spent on the hand soldering of all the thru-hole components.

So, IF you TRY really hard and you really WANT to, you can still build quality, budget components in the UK

NSMT PSM Loudspeaker

If I say, this is possibly one of the least impressive Hi Fi speakers I have heard, you may well stop reading at this point. That would possibly be a mistake.

The NSMT PSM (like its smaller brother that we have had on demonstration for a little while) is a totally musical speaker. A speaker that does not shout ‘look at me’ every time it plays. It is science totally subservient to the art form it is reproducing. If you want music to engross you, have complexity rendered intelligble, hear the the power and tonality of acoustic instrumentation – then, these may be the best speakers you ever hear.

So, definitely not for everyone, but the sort of self effacing masterful reproduction that many of us have been looking for for years.

Available from £4,600 depending on version & finish
