They both cost about the same to build ($100, I think) but what would sound the best for the money? I a little bit of a bass head, and I only listen to classic rock/metal. It will be running my HD555's.

The Millett (two Ts in Millett

) costs more like $200 to build.

I believe i spent substantially less than $100 on my Millett.

Board: $18

100k step attenuator: $16

Tube Sockets: $0.75/ea

Power caps: Around $2 (already had them, bought them cheaply)

Film caps: About 80 cents

buf634 x2: eh, $12ish.

Tubes: $2.80/ea

CRDs: $1.75/ea iirc

Elna Silmic II output caps: $1.75/ea

Neutrik output jack: $2ish? I forget.

Small passives: I'll be generous and say $3.

Like $65, not including shipping costs.

No enclosure yet - that hammond everyone likes is, what, $18? I'll probably build something from scratch.

Power regulator has about $1 in it. lm317, three 1n4001, two resistors, 100uf 35v electrolytic, 2.2uf 35v tant.

Power is supplied by a 30vdc 500ma brick i paid $2 for at a thrift store.

Where do you get the $200 number from? I can see how you could spend $100+ after using all-boutique parts, but $200?

The only corners i intentionally cut were in using five 330uf 35v general-purpose caps i already had on hand for power, two 470uf 16v low-esr caps for cathode bypass, and high quality mylar & foil caps (that i have pounds of) in all the film positions. I'm not the tinyest bit disappointed with the results, and will post RMAA results the next time i revive my windows machine. I haven't booted it in 18 months and i think the hardware is in some sort of distress.

I have both. With HD580s the Millet Is vastly superior IMO. It's like bathing in gravy and getting a rub down by beautiful Polynesian girls while the live band plays in the corner.

My tantalum cap costs twice as much as your whole power section. Same with a National LM317

Around $90 parts cost + case + parts mounted to the case + hardware + power supply + shipping costs can add up to $200.

My tantalum cap is Kemet and my LM317T is National. I'm just a better shopper than you are.

(well, maybe you have a much bigger tant than i do. I decided against my 47uf tants on the output.)

One of these days I'll roll out the $400 Millett but for now the $300 version will have to do, actually it's up to about $325 now with the DBs.

And while I have no doubt that your sub $100 Millett is the king of the bang for your buck options it's probably not practical to assume that every one can find parts as cheaply as you did. A very realistic nubmer for the Millett is $150 though and I'd say that's not a bad number for a wall powered PIMETA either. Both are great amps so instead of choosing I built both, more than once

My 2¢,

Yeah, I do agree that if you plan on paying retail for everything, most people should expect to spend $110-$130 on the Millett, and it could easily turn into more depending on how fancy you want to get.

Plus there's collateral damage - in truth a Millett builder may want to buy a few different brands/types of tubes to find what sounds good to them, and you could end up putting together a minimum order somewhere to get an exotic output capacitor.

I spent a total of $3.50 on output caps but somehow something like $17 flew out of my bank account when i did it. It's not that i don't have anything to show for the other $14.50, but until i actually use those bits, it's just collateral damage.

Never built a pimeta but i did kit one out for a friend for christmas . . . . and he hasn't even opened the static bags . . . but i was only into it about $60 w/o power supply or enclosure. the opamps i gave him were on the cheap side tho - ad823 and ad845 - and the power capacitors were just 470uf 35v Nichicon UHE which aren't at all expensive (but a lot of bang for the buck).

It's the little things that get ya, and i don't sweat the little things. I won't spend 50% of the money on the last 1% of SQ.

This all goes back to that long stupid thread about estimated costs. I am thoroughly disgusted with myself for spending close to $30 on Xicon resistors to turn that $25 Alps rotary switch into a ladder attenuator for my M3.

Things can easily spiral out of control. People with limited budgets should tread carefully.

How'd you spend so much money on the diamond buffers?
