    Well, I see your problem... you've got a quarter in there that must've shorted something out! ;-)

    No, no.no. I contacted Emoiva support with that very thought in mind, they told me to leave the quarter in there or I'll only get "1/4" of the output I should. ;)

    I got an Atlantic Technology A-2000 7 channel amp today. This thing is a beast at 76lbs. Rated 120x7. It was a steal at $600 ($1499 retail) so I had to try it out. It's going back due to a buzzing coming out of all 7 speakers, and they don't have another, oh well...thought I would snap some pics anyways.

    They are made by Eastech, the same OEM that manufactures the Parasound classic, and Audio Refinement amps. Odd thing I noticed inside, is that there are 8 10,000uf caps inside, odd since AT claims 18,000uf per channel for a total of 126,000uf:mad:

    They probably play the same game as Parasound where they count all the little caps too. Still, that seems like a big difference. Over 40,000. Unless all those little blue caps are 1000-2000uf, that's a lot to make up in small caps.

    This is another reason why it's important to survey the guts so you'll know what you're buying (or bought). I pop the hood of virtually everything I buy. Most of the time I don't know what the hell I'm looking at, but I can tell high quality parts from crappy parts.

    Been going through some old files on the computer and found these. I used this for a while but I was in a transitional phase with my big system at the time and it was kinda wasted with what I had so sold it.

    Not as initimidating as the ~60lb Sony SCD-777ES i used for a while or as elegant as the XA7ES I still use as a transport but a really pretty piece in person and the kind of statement piece that Sony does every once in a while to just show that they can. Been a while since I looked through the whole thread so sorry if I missed one of these already being posted.

    Attached are the 'guts' pictures and then links to a couple of glamor shots I used when selling it.

    Not all of you get excited by Sony equipment, but I am a big fan of the really good Sony ES gear. I finally got some gut pics of my E80ES preamp. This thing has some really impressive build quality considering it was mass produced. The whole preamp weighs more than 25lbs and has the famed "G-base" which is a thick composite of calcium, polyester, who knows what else. Its like a rock! Non resonant, non conductive, ideal for audio.

    Nice clean front.

    **** End, Plenty of inputs!

    E80ESback.jpg

    Inside shot. Nice an clean. Easy to work on. Separate boards for power, phono, main (input/gain), and balanced in/out.

    E80ESin1.jpg

    Easy access to the main board from below. Can anyone say mods?

    E80ESbottom.jpg

    Power supply section. Separate trannys for analog (big one) and digital (smaller one). More capacitance than some receivers! Nice big 10,000uf (x2) caps for the analog supply.

    E80ESpower.jpg

    Here is what makes this preamp really shine. It has a great phono section! This is probably one of the best phono sections to be found in a mainstream solid state preamp. I have some plans for this section including replacing the coupling caps with Blackgate NX, upgrading the opamps, and upgrading the power supply caps (yes, the phono board has its own regulators and filter caps).

    E80ESphono.jpg

    Is this the best preamp out there? No, definitely not. But it is damn nice sounding. Very very quiet, tons of inputs, NO input crosstalk, excellent build quality/reliablity, a great phono stage, AND remote controllable! That's everything I need.

    Greetings,
    This is one of my favorite threads on any forum. I just had to sign up to make a contribution. You really get to see what you pay for.

    Below is some comparison shots between the once $6000 Gryphon Tabu Century, and the Danish made NAD S300 integrated (which I own and love), including the use of the same volume pot and Sanken output devices.

    Welcome to the forum MusicMagic. Thanks for sharing the pics.

    How do those sanken output devices rank as far as transitors go? Those are the same brand that I have in a couple of my proton amps. Even the capacitors look like they might be the same in my protons? here is a couple pics of a D-1200. It uses 16 sanken output transistors.

    Well, I just pulled off the impossible by doing a double-blind comparison all by myself, purely by virtue of the fact that I completely and stupidly forgot what I did last. I guess that getting old does have its advantages after all :D

    Interesting,they both have almost identical board layouts and parts. Me thinks they were designed by the same person(s).

    Maybe you already know this but Proton and NAD were related back then. Much like AMC and NAD are to a certain extent today. So parts and topologies are similar.

    Thanks guys,
    It really is a beast weighing in @ 60LB. As far as the transistors go, I've read that these Sankens are very well regarded, but since I haven't experimented with DIY projects by switching them out, I can't say how they affect the overall performance. The caps are 10,000uf each, and come from a company called nichicon. I beleive the two amps ressemble much more than a mere coorporate relationship. The engineering appears too similar if not identical.

    Thanks for the info. I checked a minute ago and yes the caps in 2 of my protons are nichicons also. The caps in my little 40 watt intregated D-540 amp are 10,0000uf and 4700uf. The big caps in the D-1200 in the earlier post are 20,000uf.

    Here is a few pics of the little 40 watt proton, Note the nice sized dual transformers. Not exactly sure what these actually bench test out at, but I can tell you for sure that its a lot more than 40wpc lol. and there bridgeable for mono use. And they are dirt cheap on ebay if someone is looking for a pair of decent amps to bridge mono for your 2 channel system on the cheap, I cant think of a better way.

    I love the Proton DPD amps...I have 2 d-1200's and 2 AA-1150's...when I set the 2 AA1150's up in the bedroom I will peel off the covers and see how close in construction they are to the d-1200's ( I know they are a dual mono design like the d-1200 but they are not bridgeable )

    I will also pop the top on one of my RF2000 amps...they have two 42,000uf huge caps inside and a 1,000 volt-ampere rated toroidal transformer too.

    This phono stage technically went out of production in the early 2000's. However this is 1 of 4 that were just built this year by Ron. Thanks to CP member Spacedeckman I was able to steal one!
