Accuphase Integrated Amplifier E-460

Of Long Standing Nobility
By Holger Biermann

For quite some time sonic revolutions have not been on Accuphase’s agenda.
The Japanese are rather commemorating evolution, i.e. the continuous
betterment of the already good. And the new E-460 is arguably the mostsplendid implementation of this noble tradition.
In some way time is moving at a different pace there in Yokohama where
Accuphase has the headquarters. About 70 employees are working, tweaking andresearching in an entrepreneurial sector where the air has become pretty thin thesedays: the absolute High-End. Since the Japanese – with evidently rare persistence –stick to the tried and tested regarding technology and design, relatively newcomponents, like in this case the E-460, are more or less conveying a déjà vuexperience. Even the digital volume level indicator, which its predecessor E-450 does
not have, has already been gracing several power stations from Accuphase, like forinstance the monophonic amplifier M-100 from the year 1981 - (see also “Vor 30Jahren” [30 years ago] on page 10).
The preoccupation with components from Accuphase, i.e. this wonderfully lush
click when selecting the inputs or the still unique sense of solidity I perceive whenturning the volume knob is every time inducing in me the languorous feeling of“coming home”. Similar to what Mercedes-Benz intent with the S-Class, Accuphase
too is taking the time of about four years until they are to launch a successor. And inspite of the rather long developmental period the differences are seemingly not reallybig. By the way, P.I.A. [the German Accuphase distributor] is providing a mostinteresting retrospect into the history of Accuphase. The link www.pia-hifi.de/History
allows you to browse a wonderful vintage compendium as well as instruction manuals.
All cut from the same cloth?
As we know from the past decades the differences between the E-460 and its various
predecessors are not really spectacular. The connections are identical and likewise
the weight, power supply and average output power. 201 W into 8 Ohm respectively
332 W into 4 Ohm are almost exactly corresponding with those figures of the E-450and E-408. Then it goes without saying that these amps nearly look alike but that’s
part of the traditional concept.
Back to MOSFETs
Nevertheless, one has to take a closer look in order realise that the engineers at
Accuphase have indeed accomplished some remarkable changes. First, there is theremote commander unit which is now made of metal instead of the hitherto rather
unworthy plastic material. Then there are a number of down-sized circuit boards
inside which by means of SMD technology are to counter earlier critics who have1

been complaining about some signal paths within the circuitry being too long. We
discover a fine tuning also in the processor-controlled AAVA volume control which is
now generating even lesser noise, owing to more modern parts employed. In
particular however the engineers have returned to the comforting, warm sound of
MOSFETs. A step into the right direction because it’s without question that theseparticular solid-state devices have after all founded the sonic reputation of the big
amplifiers from Accuphase.
Yet apart from all this progress it would make sense to also reconsider thealready well-proven features, for example the pre-out function. An additional power
amplifier could be connected here in order to get the best possible sound from one’s
speakers in a bi-amplified setup. In the past couple of months STEREOPLAY hasgone through quite a few experiments in various configurations which eventually led
us to the conclusion that in nearly all cases the sonic advantages of this mode ofoperation are clearly compensating the extra expenses. Since all amplifiers
respectively power stages from Accuphase (including the integrated ones) come witha built-in gain factor of precisely 28 dB, there will never occur the problem of differing
volume levels between the driven frequency ranges (high and low) when using any
additional Accuphase power amp.
The largely balanced design of the E-460 implies the preferred use ofbalanced connection leads. Well, we cannot fully agree with this because during ourlistening tests we found the classic RCA leads in no way inferior to the XLR variants.
In fact, the opposite is true.
The two installation ports at the rear panel of the E-460 should absolutely be
regarded as an invitation for musical enjoyment in form of the excellent phono stage
AD-20 or of the even more interesting D/A converter board DAC-30. We had ample
time to audition the AD-20 as it was part of an extended E-450 test some time ago.
This is why for this review we’ve dedicated ourselves more intensively to the DAC-30.
Put in a nutshell: this option board sounds marvellously detailed and open, no matter
which digital data processing format came in from the source. We took theT+A DAC 8 (tested in issue 09/2011) for comparison purposes whereupon both wereinvolved in a most challenging duel. In the end the Accuphase DAC-30 won by aslight margin owing to its better rendition of low-level dynamics.
Gentle power
Anyway, whether T+A converter or option board, the new Accuphase integrated madequite clear right from the start that it inherited the power directly from its predecessors.
In the meantime a hard disk with music from vinyl sampled to24/192 kHz has taken a permanent residence in our listening room. Among manyothers it also contains such bizarre pieces like Charlie Antolini’s “Knock Out”.
Although, musically speaking, of rather humble value I must admit that I listened tothis drummer show with once again great enjoyment. The E-460 managed tohammer the load of drum beats into our listening room with verve, great precisionand stunningly powerful nonetheless. Well, I got almost carried away by the illusion of“live”!
Certainly, it was not only the sheer power fascinating me, but even more sothe ease the E-460 is able to convey. With its rather warm yet well tempered andperfectly executed rendition it is to overwhelm the listener with wonderful music.
Voices are a pure joy because this amp has got the ability to push the envelope very2far without ever becoming sonically obtrusive. At the end of a hectic day in our offices
I found myself still sunken in music for another half an hour or so – and yes, I was toowe this to the E-460.
The beauty of the sound is reminding me of very good valve amplifiers, its
energy potential however is in a quite different league: how explosive and stunningly
detailed the E-460 could unravel the percussions in Monty Alexander’s “HurricaneCome And Gone” was simply breathtaking. Whilst its predecessor E-450 may havestill got the virtual attitude of a “bruiser” the successor presents itself distinctly more
cultivated, matured and balanced. Indeed, the engineers at Accuphase haveachieved a brilliant fine-tuning which without any doubt makes the E-460 the best
Accuphase amplifier I’ve heard to this date!
SummaryThe E-460 is further enhancing the success story of the big Accuphase amplifiers.
Sonically on the smoother and more subtle side when compared to its predecessors
it is to outperform each of the amplifiers below 10,000 Euro that have so far beentested by STEREOPLAY. This integrated amplifier is the audiophile’s dream.
