I just ordered 4 ohm Tekton double impact SE speakers and am trying to decide between Parasound A21+ vs Zonemaster2350. One is A/AB vs D Class. Also are there any current AVR that could measure up? Thanks everyone!!!!
 
I'd imagine the A21+ will have lower distortion, no idea if it would be audible or not. Those speakers have sensitivity of 99 dB at 2W. You could get by with 25 Watts I think unless you want to go deaf.
 
And gear soundstage - I looked at the Parasound 200 but was told 110 w at 4 ohms may not pull it the resolution at low volume

I'm highly skeptical of that advice, it wreaks of something salespeople say to upsell with no basis in fact. I would try the 200 first. The built-in power amp will probably be fine, but if it turns out to be insufficient then you still have a decent pre-amp.
 
I agree, that advice is nonsense. The 200 integrated is 0.05% THD at rated power into 4 Ohms. I'm pretty sure the guys at Parasound know how to design a class AB amp that doesn't have severe crossover distortion. I would try it.
 
Not that it makes any difference, but it's a class D using a module from Pascal Audio. I think it's this U-PRO2S.

Those two are like comparing apples and oranges. A21+ is designed entirely with playing music in mind with Curl's attempts to shape harmonics to his philosophy. The ZoneMaster series is designed towards high power distributed amplifier applications to drive multiple speakers/zones. Either of them has enough power to get sound out of any speakers but will behave differently depending on speakers.

Parasound uses less than ideal Pascal modules for their Class D, not their area of expertise.

The NewClassic 200 uses a Class D Pascal module and is a lower tier lineup to the Halo series with some component compromises. In this particular model to keep the thin profile and costs down, the power supply seems to be constrained leading to no head room (same power into 4 or 8 ohms). So, it is likely current constrained. If you are driving full range speakers that need a lot of current in the lower range, then the already anemic 110W won't get it to high volumes. Might be Ok with low volume listening. But you are not getting the state-of-the-art in either the pre-amp or the power amp.

A21+ if you can afford it or A23+ instead of the NewClassic or ZoneMaster series.
 
I recently had a back-to-back comparison of the Zonemaster 2350 and the A23+ driving my 4-Ohm Pendragons. The 2350 was very accurate but sounded thin. The A23+ was much more emotionally engaging with a richer sound while maintaining nice control and accuracy.

I haven’t tried the 21+ but I expect the extra power would make for an excellent pairing with your DIs.

Save yourself $1000 and just get an Anthem MCA amp. Top notch quality, reliability and a great company to deal with. I have to MCA amps going on 15-20 yrs old, both still work flawlessly.
I have had various Parasound equipment (decent in the past,, not so much these days), always seems to be something goes wrong. Company support used to be good, now not so much. They are good at saying there is no issue with a product, even though other people report the same issues. I would not trust their repair department one bit. I'll quit talking about Parasound because it probably sounds like i'm bashing them, i don't mean to. I just have zero faith in the company and products as of lately.

Just save yourself any headaches and money, go with Anthem. There are many fine amplifiers out in the market today. When i factor in quality, cost, reliability, customer service etc, Hands down Anthem gets my vote.
 
The Parasound A23 should give you all the power you need. It puts our 225w into 4 ohms. I used to drive a pair or Paradigm Studio 100’s with one. The system sounded great. There are several on usaudiomart right now.

Unfortunately, these kinds of generalizations on the forums do more harm than good. It becomes more like Seagate vs WD debates depending on the last anecdotal experience of the individual for specific models.

I do rely on online forums to judge the vendor and equipment from user feedback and problem reports. With that you get to learn to filter out noise and individual gripes that could be anecdotal. Over a period of time, those do get normalized to what is likely to be the case. You learn to triangulate from multiple sources including this forum opinions and measurements.

You can say they are not as good as they used to be for almost any company. You buy one thing that lasts for a long time and because of that you buy a different one and it doesn't last as long and there you go.

One thing that has remained constant is praise for durability and Parasound customer service especially for currently selling equipment. One problem companies like Parasound with equipment that lasts for decades is the availability of service and parts. Like good cars. They also run into problems when out of necessity, they are forced to bring out different-tier equipment to meet lower price points. They also do well in some types of equipment and not others.

Discussions like this one are typical:

https://forum.audiogon.com/discussions/parasound-service-problems

But the OP of the Audiogon thread could very well paraphrase his anecdotal experience to Parasound sucks. But would that be valid?

I would say the quality and build of their Halo amps are the one of the best you can have for long term durability and service. You can nitpick on their design philosophy or the way they write their specs but not the quality. Analog pre-amps have also been decent but not without some issues. Things get a little murkier in their more complicated equipment like the Halo Integrated but as far as I know there are no endemic problems and service takes care of it.

In terms of accessibility, they are active and respond reasonably. The one time I corresponded with their team, the CEO Richard Schram himself took over the conversation and went to great pains to explain their design/build philosophy and rationale for what they had. So, they still have the boutique company flavor. I think they only produce in lots of hundreds or a thousand or so for the size of their market.

I would say some of the same things apply to Anthem as well. They have gone through their up and downs. There is a loyal following for their amps. The customer service, however good they might be can get overwhelmed by poorly released product like what has been happening with the AVP 70.

I have heard good things about Anthem in the past and poor things about them in the recent history.

So, I would say the two are really like Seagate vs WD in hard-drives. You get very reliable stuff for most, you get some bad anecdotal evidence. You get some "bad apple" models once in a while when they try something new, etc.

The difference between them is really the difference in their design and build philosophy as well as their pricing. Anthem would be more favorable in Canada and Parasound would be more favorable in the US for comparable equipment. Have always felt Anthem was bit overpriced for what they had.

People in HT (which includes Anthem Pre/Pro fans) are equally happy with the Monolith amps for multi-channel.

Bottom line: It is probably better to go with evaluations and feedback on specific models of any company than be brand loyal to any one. Reliability and service issues get factored into those discussions. Just like Seagate and WD.
