Nakamichi PA-7E?
 
I found a Nakamichi PA-7E for sale for 9900SEK (1102/$1428/884).
Nakamichi PA-7E

Is it a good amplifier?
I currently just have a pair of Mar-Kel70eN speakers but this summer I will build something bigger with more headroom and dynamic capabilities. Would this be a good amplifier for me or are there better amplifiers out there for the same price?

you can hardly buy something designed by Papa , for less than 1K1

if you need that power , go for it

personally , I prefer less powerful amps , paired with efficient spks

Rullknufs 10th May 2012 07:48 PM

I'm not sure if I need it, but dynamic headroom is always good I suppose?

As for speakers I am looking at the Edingdales -> Edingdale Speakers - World-Designs-Forum

WDF is acting funny , at least I can't reach it now

regarding headroom - agree , but First Watt is always sweeter in case of lesser muscles amp

Could you briefly describe the First Watt for me?

FIRST WATT

everything is written there

The F5 Turbo looks interesting. I think 25 W @8ohm might be a little too little for my needs. But 50 will probably be enough. I'll spend some time reading about the F5 and the F5 Turbo.

I don't think I can afford to buy a new one (I'm a poor school student) but how much would it cost to DIY one? Are they hard to build?

Zen Mod 10th May 2012 08:54 PM

everyone is building F5 and variants ;)

regarding cost ....... I'll let someone closer to Sweden to give you an answer .....


in any case - that Nak is more than decent amp , whatever price it is

I think you might experience a jaw-dropping surprise with F5's 25W of Class-A. Sure, relatively efficient speakers help if you're into generating lots of SPL for the neighbours. But hey - I've driven the notoriously SPL "poor" electrostats with it, and never thought I needed more. To each it's own, I suppose.

As far as DIY costs: With all Class-A amps your major material expense are the heatsinks, and the overall major expense is the heatsinks + case/enclosure fabrication. Amp itself, incl. the transformer and caps (PSU), is very little compared to metalworks.

If the build cost is a concern, not to mention the running cost and heat that it generates (which, in Sweden, might be a blessing! ;)), maybe you are in the wrong camp altogether? Maybe a conservative class-AB? Google for Naim/Avondale kits for example, and you're set.

I have bought 2 of these. Each with a channel out for under $400 USD. I sold the power supply and working channel on eBay for a couple hundred and built F5 in the chassis using the nice heatsinks. To me it was worth the $200 USD for the metal work and the F5 is really great. They have enough heatsinking for a small F5 Turbo if you need 50 Watts.
I really never listened to the PA7 amps so I don't know how they stack up. But I sure like the F5.
