Delicate sound of thunder (sounds like little amp; performs like big amp).
Good detailing and an overall very clear sound.
Doesn't sound bright.
Capable of turning bass rythm into pure drive.
Analog sound may be preferred by some.
A lot of 'bang for the buck' . See weaknesses.
Sound 'live'...

Special sound!
Needs carefull matching (could pose a real head ache with A/V-equipment).
Harshness can be detected at high volumes.
Not dynamic enough for everybody.
A lot of 'bang for the buck'- but this is not what the Carver A-500x is best at.
The constant hum is annoying!! Aren't audible when music is playing.

I am from Denmark, and purchased two of these amps (having a pair of Technics SB-M1000, I really need power to kick them into life), so 900 USD in total (used). They came with some cables and a pre-amplifier; Carver CT-26v and it sounded so horrible in 2-channel that, well... I bought a new pre-amplifier: Technics SU-C1000. This was far better, but suddenly the A-500x sounded delayed in transients. It is of my understanding, Bob Carver developed his power amplifiers with tube pre-amplifiers. So a year past and finally I bought a third pre-amplifier. A tube/valve pre-amp called Audio Mirror TP4A. Then the Carvers shone. They run considerably more hot with the tube pre-amp. Maybe the ground noise form the tubes keeps the transistors more 'ready'? Anyway, the A-500x revieled itself as quite detailed and with lots of headroom, and with no delay in transients. Eventhough I am bi-amping these units into 6ohms speakers, I never feel that I have immense power handling. I just do. This is the one point, which is different with the Carvers. It doesn't sound powerfull - other powerfull power amplifiers often sounds 'rock solid' - but not the Carvers. Here is the delicate sound of thunder.
Bying these units used, I still have experienced a harshness; but this was with the Technics SU-C1000, and only when I turned up the volume - with the Audio Mirror TP4A the hasrhness has 90% disappeared. The bass reproduction could be better. It is not exceptionally low nor tight, but it is acceptable. The highs are close to 'sweet', because it sounds mild and detailed. The midrange is good and a little 'warm' sounding. Almost any kind of horn (trumpets, sax, french horn etc.) sounds 'right'! Compared to the Luxman M-383 (200W, 8ohm), the A-500x is more detailed and clear. Compared to a SiriuS DM100 (100W, 8ohm) it has a hard time keeping up - but it is still more warm sounding, and with oozes of drive, it really got that air guitar factor.
The Carver A-500x is a strange brew. It just kind of is there. With a good signal and pre-amp it sounds good. With a bad ditto, it sounds bad. The overall sound is very clear, and I haven't detected any muddiness or murkiness. It is not a musical power amp.
So, A-500x is very powerfull, but doesn't sounds powerfull. It sounds warm, but it isn't musical. It has good detail and headroom, but it isn't analytical. It just kind of is there, but then again, it isn't neutral(...). It sounds clear, but it isn't what one might call 'open'.

Who should buy a Carver A-500x: Hi-fi enthusiast on a budget and the patience to match them with the right pre-amp. My claim is, you haven't heard what A-500x is capable of, if you haven't heard the with a tube pre-amp. But these Carvers are not good enough for an audiophile, hence they can everything rather well, but nothing (except power) exceptionally good. Although I must add, I have a hard time finding out, what amplifier I should buy next; while I'm used to (and happy with) the Carvers special sound. So my plan for the moment is to upgrade the Carvers. First of all, the potentiometers on the back got to go. These are, as far as I can tell, 'of the rack' ((really!!!) poor quality). Also, there is a problem with hum. This is from the transformator, and I cannot belive, this has no influence on the sound. So a better power supply is next step. With these two upgrades, it might be a lot better. And it might not.

A return to the special sound: The sound of these power amps are, in my opinion, to prefer with blues, jazz and soft rock; and some fine classical music. Heavy rock and big orchestral arrangements are let down by the lack of impact (keep in mind, my speakers also have these tendencies, but hearing them in combination with other power amplifiers has maked me convinced, it is not just the speakers). Used for A/V I'm not sure. Many A/V-products sounds a little hard, a little bright and a little metallic; great for movies, but that kind of sound is not a good match for the Carver. It will really make it scream!

Listening mostly to LPs through a tube pre-amp, the sound is very involving. I think, if you match the A-500x with a Croft Vitale, you got a combo that will sing. The Vitale are inexpensive and have a pair of tubes, so even this is possible to run on a budget. And strangely, a pair of easy driven speakers might be the right choice; though my speakers aren't exactly easy to drive.

This is the end: The sound of 'little' or 'weak' amplifier is present, but it never gets nervous og 'jumpy' - and it never becomes short of breath. It just plays smoothly; LP/tube-like and with fairly good dynamics.
So, when you are sitting quietly enjoying those delicate sounds, then suddenly there is a transient, and this power amplifier will blow your house down, and then you're sitting there, wondering what happened, while the A-500x sounds oh so delicate once more.

Neat design, Cool VU Meters, Excellent Bass Response, Smooth Mids & Hi's, Infinite Dynamic Headroom!

*NONE*

When I first got the A-500x I was pleased with the classic Carver appearance. The front panel is really neat looking with the twin lighted VU meters! The bass is tight and strong. The treble and midrange is smooth and pleasing to the ear. It does not seem edgy in my opinion. It is much quiter then the older Carver amplifiers. There is no triac buzz like the older Magnetic Field designs. I like my A-500x so much I would like to buy another one someday!

Sonically none. It would have been better engineering if the bulbs that light the meters were housed by snap-in or twist-in sockets. Replacement mandates de-solder of burned-out lamp,solder-in of new.

I replaced my Carver M-400 with the A-500X to power my (Carver)AL-III's. They are the front L and R speakers in my home theater setup. Simply incredible. (A bridged output A-220 powers the center, a Polk CS-400i with equal splendor while a Harmon/Kardon Citation 24 keeps up to power the rear dipole Atlantic Technologies surrounds) They simply provide all the power you will ever need and more in a normal sized (probably I'd guess up to 20' X 20'), listening area using these power hungry ribbon speakers.

Nothing in this power range.

Awesome power, never runs out of reserve.

Not as well built as the competition

I use one to drive my NHT 2.9s. These are fairly low efficiency (86 db/W/m), but the Carver never has problems cleanly exceeding my pain thresh hold. I won't say that it sounds any different from the competition. But it does all I need. absolutely no complaints. Has more power than I can use. The only time I have over driven this amp was when I was experimenting to see how loud it could go. I paid a measly $524 for mine from One Call.

clean power, runs cool

The A500X is an excellent amp, very clean & powerful yet it barely gets warm. It is the high-performance sports car of power amps!
I was very lucky to find an A500X brand new for $600 2 months ago. If you can find on of these buy it. Nothing even comes close for the price.
I'm using it to drive a pair of Cervin Vega E-715s, awesome bass. Highly recommended.

I bought the A-500x with intentions of a high piece amp. I have nothing but excellent comments for this piece. It exceeded all of my expectations. I have had several (4) other amps/combos/etc.. in the past and this is the best one yet. It puts out CLEAN wattage and is a great value for the dollar. I would recommend this for almost any audio enthusiast. 250 watts/channel really comes ion useful. A nice feature that it has is that each channel is fused independantly of the other :) Haha. This piece truly kicks some major ass.

Lots of power and headroom - a clean, fast solid-state amp that's a very good value for the money.

Not many. Doesn't have quite the depth of detail of good amps costing 3x-4x as much. Not a tube sound, of course. But it CAN take spade lugs... see below

First, a note to everyone who's had a problem with spade lugs on the A-500x. As you've seen, the problem with the binding posts is that they're protected by small collars on top & bottom that get in the way of the spade lug. (I presume they're there to prevent anything touching a bare wire wrapped on the post.) The deal is, those little collars are PLASTIC! So you can do a quick & easy little home mod to fix this:

- Unplug the amp and park it face down (well cushioned) in a well-lighted work area
- Grab a sturdy X-acto knife and a candle (or lighter)
- Look at the binding post and note that there's a top collar and a bottom one. You just need to remove the bottom one to get a spade lug on the post.
- Heat up the X-acto knife blade, and use it to saw into the bottom of that collar. You'll need to heat, saw, heat, saw, perhaps a dozen times to carve that little guy off.
- Smooth off the cut-off ridge, and be sure to clean up any little plastic shreds
- Repeat for the other post

I did this the first week I had my amp, hooked up some DH Labs Silver Streak cables with spades, and enjoyed it for two years.

Just for reference, I eventually replaced the Carver with a Proceed HPA-2 amplifier, which lists at $3500. (Proceed is one of the Madrigal brands; one high-end reviewer referred to this amp as a "nuclear reactor", it really rocks.) Recently I hooked the Carver back up to my system, and found that it still held up very well. The sound is well-balanced overall, with clear highs and solid bass.

The Carver A-500x is a THX certified 250W/ch stereo amplifier. This amp has enough guts to drive the most demanding speaker loads, and with my Paradigm Reference Studio/100s it's a perfect match. The amp itself is very neutral and appears to add no colorations of any kind. The VU meters on the front panel give a nice indication of the approximate power load going to the speakers. The only downside to this amp is that the binding posts are two way and allow only bare wire or single banana plugs for connections. Other than that this is an excellent amplifer and I will most likely get Carver's three channel version of this amp (the A-753x) to power the remaining speakers in my HT.

I just purchased this amp from Circuit City -- $599 on sale. I couldn't pass it up! It is integrating very nicely into my system. I level matched all 7 channels in my system last night with my Radio Shack sound meter.
The Carver is now the main amp in my Yamaha 2092/Def Tech BP2002 system. The Yamaha receiver has internal amplification for 5 channels at 100 watts and 2 front effects at 30 watts each. With the Carver in place powering the front L/R channels, I'm using the 5 available 100 channels from the Yamaha to power everything else. The two 30 watt on-board amps are now unused. This may be over kill but I LIKE IT!

The sound is powerful & clean. Not the Yamaha's amps were bad -- I just wanted more.
