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.

@milpai at this level it takes at least 24 hours for a power cable swap for system to settle.

@lalitk , I think that would be fair then, because I really gave the cord only 4 hours.

@dpac996 , I will plug the cord to some appliance that runs 24 X 7 and then decide in a few weeks. 
 

But, TBH, I am already loving what I am hearing. I went back and read my concerns when I started this thread. All those go out of the window - truncated treble, low power for my speakers, lost dynamics due to stepping down from 250 watts to 50 watts. And the biggest one was a comment I read on the forums somewhere - Accuphase Class A is “polite”, so I chose Class AB.

My accuphase m 1000 has 2 power cords comming out of it like the old carver tfm 75  they are wired in from factory and I would have to take it apart to put an ice plug in it  I do love the digital meters hitting 1500 plus watts.enjoy the search.and the music

"amp is fully broken-in"

Accuphase amps are always shipped by the factory after couple of days of break-in, and final tests w/ archiving test data. 

Till date I have seen the power needles go to “10” (a bit short). It was already 83dB on my phone’s decibel meter. So pretty loud. But it does not seem as loud or noisy, that I have to turn the volume down. Most of the time the needle is between 0.1and 5. Since my speakers are 4 ohm load, that 0.1, 1, 5, 10 etc corresponds to the actual watts the speakers are using. I have set the gain to -12dB on the amp. I realized that, when I initially installed the amp in the system, the volume in HQ Player was set to -6dB. I have set it to -3dB and this seems to be the final setting. This is done in HQ Player to avoid intersample overs.

Depending on your loudspeakers, how much watts have others seen their speakers consume?
