First Watt F8

[generg]

I think F8 should have 8 LEDs.....

In the style of the Alfa Romeo 4C headlight

Already a demo F8 available at Reno Hi Fi for reduced price (Sit 3, too!)
Used First Watt Products

No complete reviews of F8 yet.

I was mostly intrigued by the demo J2 price. Great deal

 

[WBS]

A great deal and a really great amp!

If you can't build a J2 or borrow one, then buy one.
Like the F4, it's one of those amps you just have to hear if you're a fan.

I built ZM’s babelfish J2 with SS parts. Assuming that’s a close experience to the production J2, I agree with you 100%!

I build EVUL's version of J2 and was not expecting what I heard.

If F8 is an upgrade, it must be fabulous.

@vdi_nenna

I would hesitate using the word "upgrade." They are both equally engaging!

 

[vdi_nenna]

According to Mr Pass, the specs are actually improved for the F8.

It is similar to the J2 amplifier, but has only one front end transistor instead of six, operated as a current feedback amplifier (CFA) as opposed to the J2's voltage feedback (VFA) differential input. This front end is more consistent with the single-ended approach to amplifier design and yields a purer second harmonic character, less distortion with lower negative feedback, greater bandwidth and higher damping factor.

Might come down to whether you like simpler signal path or balanced operation. I wouldn't predict J2 fading in the limelight.

Wouldn't be surprised if he made F8 first, then somebody said, "Why don't you make a balanced version?".

 

[vdi_nenna]

Yep, you always have an out.

Enjoy.

As has been mentioned numerous times, specs are objective while listening enjoyment is subjective. Better specs don't automatically increase subjective listening enjoyment.

 

[vdi_nenna]

OMG. Can u you drop it?
Do you always have to be right, even subjectively?

 

[vdi_nenna]

Ive built a $#^/ ton of amplifiers and listen to a %$=/ ton more. I'm very aware they sound different and ound does do not always correlate with the specs.

FW amps are all fantastic when played through the appropriate speaker. Happy?

Let out the steam.
Better out than in.

I agree. The F8 does seem like it may very well be a refined version of J2.

There are at least 2 definite improvements, and one possible negative depending how OCD you are.
2-1
Total sum = better

Hahahaha
