I am building a second system around Harbeth or ATC speaker and decided on
Accuphase for integrated amp. Between the Accuphase E600 (class A 30 watts) and E470 (class A/B 180 watts) integrated amps I am hoping someone here has compared. I heard the E470
driving ATC speakers and liked it but have no chance to audition an E600. If the E600
sonics is only mildly superior to the E470 I would rather get the latter
to avoid class A heat plus it is significantly less $$. I am in Jakarta
Indonesia where it is always hot and I prefer not have a heater
in the small 1BR apartment I live. But if the sonics gap is huge enough I
am prepared to step up. Music I listen is varied - pop, jazz, light
rock, R&B and occasionally classical orchestra.
Interesting question noelpastor. I am wondering the same thing. The E600 will definitely sound sweeter due to the Class A configuration. I have been toying with the idea of looking in to an E470 due to the increased output over my Luxman L-590AX (which is a direct competitor of the E600). From what I have been told by others who have owned both the E600 and E470, there is a slight difference in sound quality in favor of the E600 with the major difference being more power and less heat with the E470.
There is no getting away from heat generation with Class A amps and while Accuphase and Luxman generate less heat than some other Class A amps, the heat is still there. In a one bedroom apartment in Jakarta, that could provide for some "toasty" listening if the ambient temperatures are already hot.
Thanks that helps. If the difference in sound quality between the two is indeed slight I will likely pick the E470 due to its less heat and price. I have heard good things of the L590AX if I am not mistaken this is Class A so you may be making more of a sideways move with the E470. In a week or two I may be able to directly compare the E600 and E470 using ATC SCM19 speakers at the dealer this would be interesting.
You are correct, the Luxman is a Class A amp with 30 Watt output. I will soon see if its a sideways move. I just ordered an E-470 to see if they make an appreciable difference with my B&W 803 speakers.
Noelpastor, I had all pliniuses models of integrated, latest
that I recently sold was Hiato. Jeff Rowland I had was first continuum 500- not S2. Accuphase
sounds more analog than both without losing any details. Great bass, silky highs, very quiet, just one
step closer to life music. I can listen
to it without any fatigue forever. And of course build quality (even so both
plinius and hiato build like a tank) on a higher level.
Denon1 one thing I noticed with Plinius is while the integrateds (still have a 9200) are excellent mid-level stuff you really need to go to their class A separates for a jump in sonics. I remember comparing the 9200 with the M8-SA103 on same system and the difference was revelatory. I did not have rack space for a bulky amp like the SA103 so I never went that route. I look forward to getting an Accuphase integrated I have wanted to do so for a while but everytime I was ready to do something else comes up.
Update - I again visited the shop yesterday and listened to the E470 driving ATC
SCM19, source DP550, this was much much better than before with the SCM11. Hell
Freezes Over and DK Live at Paris sounded big and convincing, but with
Eva Cassidy Live at Blues Alley I felt her voice just a tiny bit thin.
Male vocals is some of the best I heard. Overall I really liked it
except I felt there was still something missing. E600 is still sealed
and vendor won't open unless I give assurance I will buy. Anyone heard
the E600 driving SCM19 8 ohms 85DB sealed box, I worry there may not be
Just a quick update. I received the E-470 today. Right out of the box, it sounds as good as the Luxman L-590AX. The Accuphase has slightly more authority on bass and it seems to feed the B&W 803s as much as they need. The difference has been subtle thus far.
More details to come later as things settle in but there is at least no perceived loss in the warmth of the Class A sound that I love.
I am extremely pleased with the E470. We used the amp to power the first North American unveiling of the Paradigm Persona 9H last month. The Rep from Paradigm was floored with how good the amp made the speakers sound compared to two other amps they had been using.
That's nice to hear. I bought the E-600 earlier this summer as a demo from a shop a close friend owns. Had it been an E-470 I'm sure I would have still pulled the trigger. My wife and I are still blown away at how beautiful it sounds, and you can play it at extremely low volume and hear every detail. The background is completely silent.
Hi guys, interesting discussion, I am looking for an integrated amp to be used with my soon to arrive Graham Audio LS 5/9, could stretch my budget to the E-370 or maybe the E-470. Can you guys tell me how these amps sound on low volume? are they quiet in operation? And also how is the headphone quality?
Greetings from Canada. I am considering replacing my all ARC tube separates with a SS integrated that can easily drive my Verity Audio Parsifal Encore (89db eff.) and the E470 is on my short list.
Are you guys using a phono and DAC cards with your E470/E600? Are those cards adding to the cost of the unit very much. I heard that they cost $2000.00 each. Anyone using them and can comment on their sonic attributes?
Would it be best to use an E470 "naked" and keep my separate phono stage ARC REF Phono 2 and Weiss DAC2. Thank You
