No doubt John. Geez, where did they pack in all that weight? Couldn't be the chassis alone. Or, could it?

Nevertheless, I can envision hefting that behemoth up the front steps... with the Ambulance arriving shortly thereafter. :-)

4 power transformers + 4 bifilar-wound chokes =  "Heavy Iron"

But all that for 100Wpc = equally heavy silliness!

But it did sound gorgeous.

No wonder it's so heavy.

John, Even though I have been involved in this hobby for quite some time, I still consider myself a novice when it comes to the more intricate aspects of Hi-Rez audio.

How come some of the best sounding amps are the 100 w/ch. amps as opposed to the mega watters in the 300-600 w/ch. range?

Am I wasting my time just going for the really powerful amplifiers?

Your opinion matters tremendously to me.

Thank you,

Mark

You can turn off your baseboard heaters in the winter and rely on this baby to keep you warm.  Like you mentioned in the article I would imagine summer listening might be kept to a minimum.  It is beautiful to look at though and no doubt even more beautiful to listen to.  Doubt I will ever hear it at a hi-fi show though due to its excessive weight.

This silly product does prove the corollary true...

If you want to make a small fortune in high end, start with a very large fortune.

Hello,

I can't help but wonder why there were no other amplifiers in the same classification mentioned in this review. In fact, the premise of the article and Antony Michaelson seem to imply there are not other class A, 100 watt or more, solid state amps on the market.

     Am i missing something obvious here? Surely companies such as Sugden, Krell, Plinius, and Pass Labs all have current offerings similar in specification.  Wouldn't it be useful to compare something to this amp? If I were looking to buy it I would certaintly be doing just that.

That is a fair point. However, comparisons can only legitimately be done with products with which the reviewer is intimately familiar. In the case of the AMS-100, this was the case with the Classe and MBL monoblocks. Though both are more powerful than the Musical Fidelity, they do bracket its price.

I had bought AMS50 and primo preamplifier one month ago.  That was a demo unit that I had bought from the distributor. I had installed the system this week. Main complaint for me is the audible noise coming from the transformer of the AMS50. At night when there is silence you can hear the hum coming from the transformer. Also no input noise on the speakers when AMS primo is fully on is at audible levels.  I think that above issues are negative points for an amplifier, but these have not been pointed out in the review. Generally when read the rewieves I never do read any comment about the above issues. IMHO these two issues are important and must be mentioned.

regards,
