In response to your email question, I say that I cannot imagine what the DNA 225 would sound like with the Adcom preamp you have. One thing is for sure, the DNA 225 with the preamps I have used, which are as follows:
SUMO ATHENA (class A output stage) sounded jumpy and exciting. The bass was darn fast and powerful, but sometimes a little boomy...but I suspect this to be a problem with the speakers I am using, which produce too much base, as well as with the back
wall interaction(it makes standing waves and sounds, boomy.) Now, I have paired it with a FIRST SOUND PRESENCE DELUXE preamp. This is preamp is tubed and it makes the DNA 225 react when it is called
for. Less exciting then before, but let me say that my system has gained a little COMPOLSURE Not a bad thing. The DNA 225 will out do the PARASOUND soundwise anyday.
If I had to classify from the lowest to the highest in the quality of sound....CARVER=sub
1K amp sound, mediocre at best, harsh sounding and pathetically weak in contrast to its high wattage designation...my amp produces 200 watts, but they are more powerful than even the 1000 watts that showed in the M 4.0 t Carver's led scale. What does that tell you about really watts? PARASOUNDS go between 1-2K range easily. They might compete with the likes of ADCOM, ARAGON, ROTEL? I have heard the 3500 has transformer humming issues....too big of a transformer, that is one of the trade backs. It supposedly produces oddles of current. The McCormack, even besides the DNA 225, which is priced a little above the 2K mark, takes the quality of sound
to levels between 2-5K (Like the SF Power 2 I had) is will give you a great sound, maybe you will not crave for upgrades anymore. Many AUDIOGONERS have McCormack
moded models as their reference, but can I say that they have PARASOUNDs or even CARVERS in the same rank? Never. The person you spoke to, he is simply trying
to defend whatever he happened to have experienced or owned. I cannot believe that anyone would keep a Carver especially the M whatever designations as their standard reference, if money was not in question.
I sold my M 4.0 t for $100 3 years ago. There is someone selling the same model for up to $400 in some sites. What a rip of an amp. I would rather run a pair of car
amps home than a Carver.
Regardless of what people defend, one needs to understand that it is all subjective. Some people favor BANG for the BUCK, and to those, a Carver might seem fine, especially if they see the wattage vs dollar ratio. Forget about Odyssey amps claiming the whole interesting article about weight/wattage/dollar calculation. Carver was at it way before....what about those Class A amps, like the Clayton that weight substantially and yet produce just 40 watts, but man, what type of 40 watts are those watts?
Having not too much money to spend, I would still skip Carvers anyday...rather fall into debt and get me something real. Never heard of the A series, but I know that thos transfer function amps were useless designs for real world purposes. Back in 1989, when I had a pair of Kappa 9, I have had the Carver M 4.0ts running monoblock, you needed to see how the Infinities ate them up for lunch. The lights would go to clipping and bang, nasty sound. Carver amps of those days were not well designed...thank God I got rid of those junkers, without damaging the speakers. Back then I did not know any better.
Guys, stop fighting over this amp, some designers are absolutely second class, older Carver corp amps are such designs that do not deserve another neuron and carpatunnel nerve injured for them.
Hope it helps.
