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.

Do you see yourself keeping the ProAc for the next 5–10 years? If the answer is yes, then go with the P-4600. But if you’re likely to move toward speakers in the 95–96 dB efficiency range in the near future, the A-48S would be my pick. If your emphasis is on building your system around musicality, go with the A-48S. For maximum flexibility, power, and long-term versatility, the P-4600 is the way to go. Both amps are truly end-game pieces for anyone who tends to keep their gear for the long haul. 

I don’t see any subs in your room. A well-matched pair like REL’s could be a fantastic addition — they would add depth, scale, and bring even more life to your setup.

When I added my Tannoy and Accuphase back in late 2018, I knew, I’ve found my forever components; the kind I could build the rest of my system around. Like @arafiq I’ve had my fair share of gear swapping… Accuphase finally got me off the merry-go-round 🙂

I've no experience with either but it would seem a 50wpc class a would heat up your room and run up your electric bill pretty nicely.

@dpac996 ,Thank you for getting back on the comparison. I am leaning towards the Accuphase.

@arafiq Your discussion with @lalitk and others actually piqued my interest in Accuphase. I am glad that you mentioned the AGDs. I did consider the Duets based on @twoleftears experience. How would you describe the sound of the AGD Audions Vs the Accuphase? Cool/Warm/etc? Yes, I do feel that an Accuphase amp will go very well with the Rhumba I have. 

@lalitk, very good question. With a high school freshman and another in college, I do plan to keep the ProAc at least for 5-8 years. They make me so happy every time I play music - in my system they are that good. But I for sure do not want to sound to be more warm. I did read a review of the Accuphase A-48S and based on it, it sounds like the A-48s might be a bit warm for my taste. You are so right - I read many a reviews and found that while these 2 amps are entry level in Accuphase's line, they are end-game amps - so some serious amps. About subs - I do not think I need them - especially with what the ProAcs do and how I have tamed the bass in my system. Yes, subs will provide even more foundation - but for the moment the money would be well spent on an amp rather than divide the amount between a nice sub and an amp. I have always checked your system from time to time and saw that Accuphase. But your Tannoys are far more efficient than my ProAcs. Hence I am also considering the Coda 8, because of price and the fact that the version 1 has a nice Class A bias. Also I have not read a single review that states that the Coda is warm.

@llg98ljk you are right about Class A and heat. But that would be the last reason for me to not go with the amp.

@milpai 

As you know I own the P4600 and my C7 Harbeths sensitivity is 86db. No problem driving these speakers. I listen to mostly Classical Symphonic and hit peaks of around 74db in my 17x15x9 room. I never exceed more than 1 watt on the meters. So I have plenty of headroom. The A/AB P4600 is biased in Class A up to 20 watts. This is a fantastic sounding amp. The only SS amp I’ve heard or owned that does not sound like SS. Just sounds natural. 

@jfrmusic ,

Yes, yours was the FIRST P-4600 post that I noticed anywhere on the internet, that can be truly deemed as a "user review". Thanks for that. And you had mentioned earlier too that your speakers hardly go beyond 1 Watt.

Sometimes I wonder, if that is the case for some speakers, then in that case would it even make a difference whether that 1 Watt came from a A-48S or the P-4600? One thing is for sure that except for 1 unfavorable "user experience" on this site, nowhere else have I noticed anything unfavorable about the Accuphase amps - be it integrated or power amps.
