Yes, the F1 is so detailed, it really pumps rock music.

Yes,

Srajan Ebaen used a tube pre-amp (Eastern Electric Mini-Max) to add some tube flavor to the detail and purity of the F1.

OMO, Sig 30 wins on solo vocals and light instrumental (my favorites). This amp adds a lot of body and dimension to solo instruments / vocalists. With the Sig 30, solo instruments and vocalists rise to the foreground (so they are a little 3D). Where I found the F1 to be a flatter image.

The F1 did better with music that requires punch, power and authority (rock). The F1 also did a better job reproducing room ambience and a large soundstage (as least when driven balanced from my Wadia).

After hearing the Sig 30, I found the F1 sound kind of cold and flat. As Tom pointed out, the addition of a tube preamp may be just what’s needed to make the F1 really shine. If money were no object, I’d love to hear the F1 paired with a balanced tube preamp.

P.S. While I enjoy listening to classical music on FM, it's not something I play on my main rig or K1000s, so I can't comment here.

The following quote is from the First Watt F2 manual, describing the difference between the F1 (balanced design) and the F2 (SET). The Sig 30 has been described by others as very SET-like in sound quality. To that end, this quote may shed some light on why the F1 and Sig 30 sound the way they do (balanced amps are know for detail, while SET are known for warmth)...

“Most customers also have no use for balanced inputs, which is
fine because the purely single-ended F2 circuit cannot use a
balanced signal in any case.

While the F1 had a crisper sounding 3rd harmonic signature, the
F2 has a richer 2nd harmonic character, one that is sufficiently
different to justify another version of a current source amplifier.“


P.S. I do not know this to be fact. This is just a guess on my part.

A week later, and I am really enjoying both amplifiers. I would confirm the comments that I made in my earlier review. I would say that the Signature 30 is even more warm and open after another week of break-in.

For the moment, I have the F1 driving a pair of Omega Revolution speakers and the Signature 30 driving my AKG K1000s, but this could easily change in the future.

I am a very happy camper with these two amps!

Thanks for those impressions

I think based on that I will stick with an offering from Pass for the type of music I listen to.

I have found that listening to radioio.com classical

http://radioio.com/radioioclassical.php

and radioio.com jazz

http://radioio.com/radioiojazz.php

on my K1000 + SAA Equinox + Signature 30 delivers very enjoyable listening for me (better than FM).

IMO you won't go wrong with the Aleph 3 or Aleph 30. Nelson Pass has really thought through the kind of circuitry (SET) needed to drive the K1000s to perfection!
post #114 of 175
Has anyone directly compared the Pass Aleph 3 to the Sig 30 or F1?

Also, is anyone looking to rid themselves of an F1?

I have an F1, no K1000s, my speakers are lower than 89db, need $$ to take a global trip, so I want to sell my F1.

You should list it in the Amplification for Sale / Trade Forum.

Congratulations! It is a great amplifier for the K1000s.

You do have a pair of K1000s, don't you?

Yeap. Mine are December 2005 production with probably less than 300 hours on them.

Consider upgrading the cabling on your K1000s. I found that it made a great difference, particularly when being driven by the FirstWatt F1.
