You are right that the wall wart is not a kiss of death.  However, Meridian could have made the chassis slightly bigger to accommodate a regulated PSU and charge like $300 - $500 more in lieu of $1250 for a dedicate unit.  Noise floor would not have been a problem given that they perform a proper shielding.  By doing so they will not short change their design and win lot more customers by doing so (Bryston BHA-1 anyone?).  Don't you a feel bit curious on how much better a "Prime" will sound with a much better PSU?  I hope you don't, b/c it will cost you more than a grand to find out.  To think of it, a DIY PSU such as the Sigma 22 maybe able to accomplish the same task for considerably much less money.

I only found out about the ifi after I bought the Prime :c

Droves?  Hardly.

 

I can afford it and still think the price is outrageous.  At half its listed price, it would still be expensive but the price could to some extent be justified by its pedigree and capabilities.  Still, I know of no other single component - which is what I want for my desktop, not a haphazard collection of boxes and cables - which meets all my requirements so well.  I also have no qualms about its ultimate quality and reliability so I will very likely pony up.

No, a wall-wart doesn't mean an amp is bad. But we're clearly in opposing views on this so it's sort of futile to try to argue further. For me, and clearly others here on Head-Fi, it constitutes meaningful info on which to not act, if I can use your words, in the specific case of the Prime. I might have considered buying the amp if it had been implemented better for its price (or if it was simply cheaper, like $500 or less), but as it is, I have no interest now in ever buying it, or anything else from Meridian now for that matter.

 

I also disagree with your statement that "impressions beat non-definitive specs". IMO, subjective impressions and specs are equally important.

Yes, that's exactly what I was saying.

Oh, I wasn't arguing.  :smile:  I simply wanted to know how the following can co-exist:  (a) wall warts resulting in poor performance; and (b) positive impressions of the Prime using a wall wart.

The answer to that isn't obvious to you? Easily-impressed listeners, or those who haven't heard better, or most generously, almost any audio product is sure to get a positive impression by at least one person, because when we're talking about subjectivity, you leave open the chance that someone somewhere will find something subjectively good to their ears, even if that something is spec'd and/or measures horribly.

Sure, in which case I would expect to come across negative impressions as well, which hasn't happened yet.  Subjectivity does swing both ways right?  :o

 

If anything, I'm simply saying that more data points are required, at least for me, and that I'm not ready to definitively rule it out in the meantime.  It's not like I'm trying to defend the unit or something.  I haven't heard it yet.

 

Also, in case we don't touch base again before tomorrow, happy holidays!  Stay warm!  :smile:

First of all - Happy Holidays to you all!

 

Regarding the comment:  "Lastly, on a personal note I've never heard proper bass reproduction from any amp that used a wall-wart. I repeat: never. Whenever I see an amp that uses a wall-wart, I expect it to have some sort of bass deficiency, and historically that expectation has always been met without fail"

 

My experience thus far with the Meridian Prime is that bass reproduction is not a problem, but that might just be the way I'm using it in my configuration.

 

a) Purely as a headphone amplifier, the bass reproduction is at least as good as the Woo Audio WA6SE, which has its own separate power supply component.  Even using my harder to drive Grado PS 1000 headphones, bass reproduction is outstanding, and power is more than plenty, as I can't get past the 2 o'clock mark in the volume knob without feeling that I'm going to really hurt my ears.  Again, I'm using the iFi on the front end of the USB chain for clean USB data/power.  And I have plugged the Prime's wall wart to my Panamax M5100-PM, which is in turn getting power from an APC UPS- the combination of all of these already delivers fairly good conditioned AC power to the Prime.

 

b) I also use the Prime as a pre-amp, connected to a Yamaha RX-1700 with a 5.1 speaker setup.  Sound quality is great and bass reproduction is of course not an issue as the Yamaha is doing the heavy work here.

 

c) I have not tried the other typical configuration which is to connect the Prime's output directly to powered speakers.  I don't have high quality powered speakers to do a meaningful test on this configuration.

That's an awfully big wall wart!

Would we be more impressed if the same contents were in a separate box that didn't plug directly into the wall?

post #130 of 241

I agree, a direct AC cable connection with a separate box would have been my preference.  I had to get creative to plug the wall wart into my Panamax M51100-PM power conditioner, as I unfortunately have other wall warts plugged into it.  However, once I was able to find room for it, I have forgotten about it and enjoyed the sound coming out of the Prime.

Merry Christmas everyone and best wishes to you and your family this Yuletide.

I am slightly bemused by the vehement criticism levelled at this product. As magazine reviews have been very positive, as have online audio websites and folks who've purchased it and contributed their thoughts in this thread. Yes, it is very expensive and could arguably have incorporated a much better power supply for the price, but we're not forced or coerced to buy it are we?!? So why not allow folks that actually own it to extol it's sonic virtues without sniping about the wall wart or the cost.

I think the wall wart is big compared to the small size of the amp.  I think it is a normal size.  I would not be very impressed with the content of a wallwart in a separate chassis at all.  Here's my thought on a good PSU design & layout and this is an older model.

Odd, you don't seem new here.   But picking nits is what we do.   For hundred and hundreds of pages.

 

Personally, $500 is the drop-dead upper limit of what I'll pay for a piece of gear with a wall-wart.   Not negotiable. 

 

Seems like a pretty big nit to me.  

post #135 of 241

Nitpick if gear is expensive and sounds mediocre, but by all accounts the Prime sounds pretty darned good, so the barrage of wall wart criticism seems a bit churlish to me. 

 

Merry Christmas.  :beerchug:
