I think from what he says budget minded would prefer assembled & tested boards to which he can add a PSU & box etc - not sure what to recommend for this.

i'd prefer a completely built unit, but if there's a design that has adequate instructiions to build a design right and thatdoesn't assume i know a lot of "surprise" stuff like resistors are directional or all the in between steps hackers skip over in trying to solve a problem instead of covering EVERY single step instead of leaving me scratching my head as to where this missing "whatchamacallit button" is where the instructions leave me that isn't there, but hidden behind two more infuriating abstract layers that can't be figured out like where the missing piece in a mechanical device belongs.

what i want is a $500 amp that has acceptable high end sound that's neither lean and clinical, nor thick and lush... that just disappears like any good gear should. i keep running in circles where i think i find a giant killer like the benchmark DAC only to find "lavry is better than that, but paradesea is better than that, but minidac is betterthen that, but wait... minidac sucks because it's too thick and forgiving... and there i go back to square 1 pulling my hair out by the roots.

if i can get a world class amp for $500, i don't mind building it as long as i'm given EVERY piece of info needed to do it right, and don't need to buy that much in test equipment too to build it. i already have a soldering iron, a drill and basic tool set... that's all i'm willing to invest in to build a lifetime amp.

if i still had my superzeros, i might not even be here and would still be dealing with the soft treble that doesn't have the same sparkle as a good aluminum dome like B&W, paradigm or my nice energys.

if i can buy it with a return policy, i might get a kingrex class D & power supply. i love the high end look, class D in both sound and environmentalism, it's within my price range, and within shouting distance of the SKA according to 6 moons.

hi.

Click on the 'PeeCeeBee' link in my signature place. If you have access to etching tools or other ways of making your own pcb then this might well meet your needs. It's simple and requires minimal manual setting, doesn't sound 'fat' or 'clinical'. Me and a few fellows here have built it with success and like its music. You may like it too.

and i get linked right back to this page. i'm starting to think noobs aren't welcome in these here parts.

Shaan's signature links are working fine at my end.

[Nico Ras]

Yep, no problem there at all.

The link just worked for me too..

link work for me too

i was originally interested in DIY amps because of simple gainclones with just 9 parts. when i start seeing pics by people i'm guessing are more experienced than me asking if they mounted everything right, memories of my NAD blowing up when my subwoofer wires shorted come back. *pop pop pop*! flash and oh all that smoke

all the other talk about making changes to power rails and filtering too make me think this might be too big a project to attempt for me. my mind is allergic to abstractions. i understand mechanics much better as you can see what's going on.

Can you see what is going on inside a combustion chamber or the ecu that controls an engine ????? You can get a good idea by the use of physics and some equipment .
same is to be said for electronics.. An audio signal is a very complex signal and it is no mean feat to design and build an amplifier that sounds good ..
It takes knowlage and expirience . If you want a quick solution buy a complete amplifier kit.. or if budget is your main concern buy somthing ready made it will cost less . if it goes wrong it will have some sort of waranty..
The knolage and expirience on this forum is second to non .. Hell some of the best audio designers in the world hang out here and give an endless amount of imformation.. Diy audio is a very rewarding hobby. Just like any foreign language it is strange at first but if you need and want to learn it will take time and paitents ... And finally it is the loud speakers that give the largest tonal variations .. DO YOU HAVe a HOBBY?? ps i am a trained qualified mechanic . I find it boring compared with audio electronics. there is always somthing new to learn and discover but remember it will take TIME and Will make your head hurt at times .. However the rewards are plenty.. There is only one way to gain expirience.. Lots of newbies on here build amplifiers they had no expirience just like yourself but are now enjoying the fruits of there labour

If you like class-D, I can't see a clear reason to look somewhere else. Class-D imo have strength and weakness. As long as you cannot see the weakness, all you have is the strength, an unbeatable strength.
