Accuphase amplifier choice


Hello All,

I have decided to upgrade my Parasound A21 amplifier looking for a more refined sound. The following are the amplifiers that I have in my mind:

Accuphase A-48s
Accuphase P-4600
Coda No. 8 (meterless)
Coda 16.0 (meterless)

Currently I am leaning largely to Accuphase. My dealer says that the Class A 48s will sound better with my ProAc D48R. But I am worried that I will lose dynamics since the Accuphase is only 50W into 8 Ohms. But it doubles all the way into 1 ohm.

The P-4600 is a higher wattage amp and I think it should be able to drive the D48R with ease because it doubles down to 2 ohm load. So I am not concerned with it's ability to drive the ProAcs.

I do have some feedback on the P-4600 from another thread here and appreciate it. But now looking for some comparisons.

Has anyone compared/experienced the Accuphase Vs Coda amplifiers? Any feedback is appreciated.

Just go with the best option you can afford. You don’t want to be sitting in your chair listening and wondering if you could have done better. 

@audphile1 , both are in the range and hence pulling the hair.

Not to be anal about it, but I was also checking the cost of electricity to run the amps based on their power specs

A48S:
Idle = 200W
In accordance with IEC62368-1 = 220 W
Stand-by = 0.3W

P-4600
Idle = 94W
In accordance with IEC62368-1 = 250 W
Stand-by = 0.3W

I told AI to calculate the monthly costs based on daily usage of 0.75hr of idle time and 3 hours playing time and here is what it came back with:

Amplifier Monthly Cost
A-48S (200W all the time) $3.60/month
P-4600 (94W idle, 250W playing) $3.94/month


@westcoastaudiophile , do you see this similar difference? How much heat is generated in summer?

@milpai 

The E-800 is a seriously capable integrated—no doubt about it. I actually considered making the jump myself, but ultimately it felt like it would be more of an interim step. For the long run, moving up to an A-48S paired with either the C-2300 or C-2900 just makes more sense. That combo feels like a true destination, not a detour.

I also sent you a PM.

@milpai People who are bringing up heat issues are probably thinking about the older class A behemoths like Krell or tube amps. As someone who owns an A80, let me just say it’s a non issue. Just make sure there’s enough clearance on all sides of the amp. 

Hello All - I've been following this thread with great interest. Always been aware of Accuphase, but always thought of myself as a Luxman guy - I own a class-A 550 AX II integrated and it's my headphone rig. The end of the OP was... "Has anyone compared/experienced the Accuphase Vs Coda amplifiers? Any feedback is appreciated." I'd be interested in pulling that thread some more if anyone has something to offer as I've got a Coda S5.5. Best amplifier I've personally owned - coupled with Aric Audio Motherload XL and high efficiency Spatial Audio M3 Sapphire's - but always thinking of chasing down a few more percent gain. Any thoughts on an Accuphase amplifier vs. my Coda would be interesting to hear. Thanks in advance and again, this has been a very interesting thread.
