Meridian Prime Headphone Amplifier Review - Page 8

post #106 of 287

I just got one of these things over at Definitive Audio in Seattle, and it sounds great! I find listening to The Beatles in Stereo with ASP 1 helpful, as it merges the right and left, and it doesn't sound as seperated as before!

Who said anything sounded bad?

Fixed.  Got the Audioquest Carbon USB A to USB mini.  Sold the Audioquest Carbon USA A to USB B.   Really loving the sound!

Agree - I don't think the wall wart has much to do with the sound quality, from my own tests and observations.  However, I'm using the iFi iUSBPower to feed the Prime with the best quality USB signal and power possible, and it does make a difference compared to just connecting directly to the computer.  I believe the wall wart is mostly used to feed the analog amplification circuits, and even when cranking the volume very high on the Prime without any music playing, my perceived noise floor is extremely low.

 

For this reason, I don't think that I'm able to justify going for the advertised Meridian Power Supply at the current price level. I have been using the iFi iUSBPower unit that costs less than $200 and is providing a clean USB power and data signal to the Prime. I have tested the sound quality and noise floor level with and without the iFi, and I can say that this little iFi unit is making a big positive difference. From my listening tests in my current configuration, I am very happy with the results and I can't think what kind of positive impact I could get from buying the Meridian Power Supply unit.

No one.  But surely no one would complain about a wall wart sounding good.

Thanks much ticos!  :smile:  I found it odd that there were so many complaints about the wall wart, and yet none of them posted their impressions of how the unit sounds with said wall wart.

I have lots of wall warts, but none of them make any sounds. None of them is attached to something as expensive as the Meridian, but never mind. If you think the sound/looks/flexibility of the unit justify the price, then fugedabout the wall wart.

I doubt that the Prime sound bad.  However, it will sound much better if they include a regulated PSU and not a wallwart for $300 more.  The upcharge of $1000 more for a better PSU is a bit much.

Honestly, I couldn't say as I haven't heard it yet.  :(  But if we're to judge a unit by it's performance, then would it not make sense to judge the wall wart in light of that as well?

Again, I think that would depend whether it improves the SQ, and by how much if it does.  I can tell you that I am eagerly awaiting an updated rectifier PSU for my WA7.  And even though it amounts to almost half of what I paid for the main unit, I consider it a worthy upgrade after having heard the difference it makes.  I realize that the dollar amounts are not the same in this case, but proportionately it's not that far off.

 

In any case, I was simply asking for impressions of how it sounds with the wall wart in use, which ticos kindly provided.  :smile:

You and me both.  I've heard so many good things about that ifi that it's getting very hard to ignore it.

No one here said anything about the sonic effect of the wall-wart. I'm pretty sure the main reason I and others complained about the wall-wart is the hassle involved to use one, whether deployed on a power strip or straight into a wall socket. Wall-warts in general are just annoying and I'm sure most people would've preferred an amp with an IEC C14 inlet for use with a more standard power cord.

 

It also screams cheapness & laziness on the part of the manufacturer for such a high-cost amp. $2K for an amp without an integrated power supply is outrageous. Most amps that come with wall-warts are less than $500. I can't think of a single >$500 desktop amp that comes with one other than the Meridian Prime.

 

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. I'd personally expect the same from the Prime.

 

And that photo of the wall-wart is a major disappointment. The Elpac wall-wart that came with the $300 (the price when it originally came out) HeadAmp Gilmore Lite is probably more than twice the weight & mass of that dinky piece.

It has not stopped people buying this piece in droves, apparently... The market takes care of itself. If enough people are willing to pay the price it is not outrageous. I can't afford to blow that kind of money on an amp with a wall wart but if other people can, good for them!

LOL, well maybe if the thing wasn't so big, people might take it with them?  Okay, okay, I'll be good and not go there.  :smile:  Still, that it does what everyone says it does is enough to make me want it.

I dunno about that... some of these IEC cables have pretty big-ass terminators on them.  I have several power cables that are the hardware equivalent of that one rude guy on flights and in movie theaters... never staying in their own personal space.  :smile:

I'll grant you that as I can't either.  But that - in and of itself - doesn't automatically invalidate the Prime as a good performer right?  Here's what I'm saying.  I can perceive that it uses a wall wart.  But at the end of the day, that does not constitute meaningful information on which to act or not act.  Now, if you were to try it out, and report back with impressions... that is information that I could make much better use of.  In short, impressions beat non-definitive specs.

Are you saying that there's a direct causal relationship?

 


 

Anyway, we've got a handful of positive impressions so far, and no negative impressions, so that does bode well.  I'm not counting that guy who sells them of course (can't remember his handle right now).  Maybe the wall wart by itself is not a kiss-of-death?
