Please tutor me on some integrated amp basics.


I’ve recently purchased Magico A3 speakers and a VPI Classic 2 SE turntable with an Ortofon Black 2M moving magnet cartridge. I have a Marantz SA 8005 CD/SACD player to play the few (maybe a hundred or so) CD’s in my possession.
I’ve mostly vinyl albums and no streaming sources. I’m next going to upgrade my old amp/preamp purchased back in the late 70’s with a new, probably integrated, one and am starting to do some research.

Here’s where I need some tutoring. A lot has changed since the seventies with the advent of digital technology. As well as I need to learn more about amplification components in the high end of audio technology. I keep running across terms I don’t understand. I’ll give you a list and if someone would be kind enough to explain these basics I’d be obliged.

For instance I was reading about the Hegel H360 integrated amp that Magico’s Alon Wolf recommended for their A3’s. The review mentioned they were a Class A/B amp, another person commented Class A’s were better, and a third person said he didn’t care for Class D amps. What do these classes signify? 

A second question is about DACs. I generally understand their purpose of the DAC, converting a digital to an analog signal. However my only digital device, the Marantz SA 8005 already has a DAC, ostensibly of good quality. The turntable ’s Ortofon cartridge would not need to play through a DAC, I presume. Would I bypass the CD’s players DAC if I purchase the higher quality Hegel H360 integrated amp?. Or could I find an equivalent integrated amp without an integral DAC?

On the other side of the equation I understand the turntable’s cartridge cannot play through the Hegel without first going through a phono stage. My old Phase Linear 4000 preamp you just plugged the turntables RCA cables into the back of the preamp and you were done. What’s that about? Do they make equivalent integrated amps to the Hegel H360 with integrated phono stages already in place, so I can just plug my turntable in as I’ve been able to do before. The amps don’t seem to be well integrated at all if you have to add a pricey phono stage to make them work, and end up having an extra DAC. That’s just me whining.

Third question is what are monoblocks, how are they used, and what are their advantages to a system? They were used at one of my speaker auditions.

I figured out the answer to what amplifier damping was myself, so I’m sparing you that one, but what does the term impedance mean? I keep coming across that.

Thank goodness I don’t have to figure out the cabling nightmare yet. Thanks for any help.

Albert doesn't advertise less expensive models but he sells all models, including custom lengths.
Ha. The Cable company wants full retail for Purist cables. Tell them to...you know. Galen Carol Audio in Texas too.
Realistic price for 3 meter Museus should be under $1k and for Poseidon a little over $1k. They should be partly similar and partly different.
Inna, if the Poseidons are just a little over $1000 maybe that's what I'll do. You haven't steered me wrong yet far as I know. I'll try and track Albert Porter down.  

Glupson. I'll get this done. My mom used to call me a "grinder" as a kid. I just grind away at things and always ask a lot of questions.  

I'd just as soon steer away from Audioquest anyway, as I think someone said they're another "made in China" company.  I'll see if I verify that.  I read the Purist Audio Design Company is homegrown. In itself that's not any guarantee of quality, but Chinese products so often are a guarantee of  the opposite. But I'm beating that horse to death.

Maybe I'll post a list of all the cable companies I've come across, here and elsewhere when I'm finished with this. It's an incredible number considering that the audiophile market has shrunk so much over the years. And each company has such a variety of cables.

Albert is nice to talk to. Yes, I bought my Neptune from him. I don't know, though, if he accepts returns for a refund, I didn't ask.
He's got half a million or so system and probably heard both Magico and Luxman, but maybe only top models. His assessment of Neptune was exactly as mine, I heard his opinion after I'd bought those cables. And his system is very different from mine and not only in cost. He always uses tube equipment and top of the line Purist cables.
Story that I heard, don't quite remember who told it, maybe in fact it was Albert telling it here on Audiogon.
Over 30 years ago a man came to a place where members of Dallas Audiophile Society were gathering, man with a cable in his hand.
At that time most of those guys used top of the like Audioquest. He said - put this cable on your equipment and you will not want to use Audioquest any more. The cable was Purist original Aqueous fluid cable and the man was the founder of Purist Audio Design.
So yes this is an authentic company.
Oh yeah, they stopped using Audioquest.
