Hmmm, good question... I think single pair in push-pull, but I need to check.

So I was wrong... there are two pairs of output transistors. The same configuration as in Ecstasy III - excellent for driving difficult loads.

Nice, thanks AudioVista

So I will resurrect this 3 Year old thread. I just bought a Rogue Audio RP-1 Pre-amp and have been looking for reasonably priced but great sounding monoblocks and totally forgot about the Dayens. I am now seriously considering them. Are they that much of an upgrade over the Ampino stereo amplifier or the Ampino integrated? Both the stereo and integrated are a lot less expensive.

The Ampino Stereo vantage are its single ended, if you need low power its great.

Can you explain that further? I don’t know what that means.

One single Pair of output transístors.

One single Pair of output transístors.

And how exactly is that an advantage over the Monoblocks? Is the integrated the only one with the single pair of output transistors or does that hold true for the Ampino stereo amp as well?

Need to decide soon. I don’t need a tone of power, so if the 35 watts per channel will suffice, then I will go that route. What are the major advantages of spending so much more on the Monoblocks compared to the stereo amp? $1600 vs $650. Am I going to hear a $1000 difference?

From Dayens website:
Stereo amp
Per channel = push/pull
"one pair of Japanese (bipolar) output transistors per channel"

Mono amp
" two pairs of Japanese (bipolar) output transistors per channel"

A SE amp have 1 pair of output transistors or only 1 output tube if is a tube amp, it have few parts and a can have a purest sound, of course the lower power is a drawback, you will need a hi sensitivity 8 ohms speaker with a benign impedance curve.

I was said the Ampino are well biased in Class A hence the low power, dont know how much. Dont be hurry, its good that you study the subject and your personal taste for a long time.

It could be more power.

You will need to search goo to find it and click image.

Are you sure?
Seems to me that se (1) and p/p (2), transistor or tube would be the same.

Maybe you missed my post above with info taken from Dayens website.
Stereo amp has a pair per channel and the mono amp has 2 pairs per channel.

Once found a amp with just 1 PNP, not a pair.

Single ended?
Firstwatt SE amps have 1 transistor, PP amps have 2.

Alright you two, so your conversation went above my head. LOL 

Lets put it in simple terms for a simple man.

In terms of pure sound quality, which amp provides the edge? Monoblocks or stereo Dayens Ampino?

Theoretically, the fewer output transistors the better they can be matched. 2 closely matched is easier than 4 or 8 or 16.
This is one reason some feel lower power amps sound better; fewer parts, less circuit for the signal to flow through.
Do all manufacturers closely match? Probably just a few (more expensive) do.
On the other hand, more transistors can mean more current (and power).

Edit: I doubt there is much difference between the 2 when used within their limits.

I have read about amps in general that some think mono amps have better separation and stereo amps have better center fill.
Expectation bias?

Go with the monos. They'll likely sound better than their stereo counterpart.

Thanks for the information.

I think I am going to keep it simple and start out with the stereo Ampino. If I feel that I need more power, will jump up to the monoblocks.

$1600 vs $650 

Too many variables, speakers easy or more more difficult load, how loud, etc.

I have a small room, 12x10, have super easy speakers to drive, ZU Audio Omen Dirty Weekends, 12ohm, 97db efficiency. And although I do listen at 97db volume levels at times to some Metallica, I think that 35 watts x 2 per channel will be plenty.
