Long-time listener's picture

I'm interested in a certain question, so this is addressed either to Herb Reichert or to anyone who can answer it. Given that the Pass Labs amp that Herb likes for its vividness has generally higher distortion than this amp, especially in the highs, I would like to know what aspect or aspects of its performance would account for that extra vividness? Genuinely curious about this. I've found that good measurements in DACs tend to correlate with what I consider good sound, but it seems much harder to make that correlation in amps.

Probably because the Pass is a push-pull Class A amp using FETs and no feedback, vs. the Bryston’s Class AB operation. If I follow Herb’s writing correctly, he seems to always prefer Class A and FETs because they result in the most transparent and vivid images, perhaps at the expense of some wallop and control on inefficient speakers. But I’m no electrical engineer.

I posted a reply here a couple of days ago, then edited it to correct a typo, upon which my post was "sent to the admins for approval" and promptly disappeared. Please could you approve my corrected spelling and reinstate the post? Or does my *speling* not make the grade for such a lofty publication? ;)

... on more than one occasion.

Yup, same here over the years.

Make sure to do it in one shot - no editing. Otherwise it ends up in the Black Hole.

I see. I was looking only at distortion levels, and I wondered, does the high frequency distortion in the Pass (which seems quite high) maybe add a little extra crackle and crunch to the sound of the cellophane, making it more vivid? (Heh heh) But I see there's more to it than that.

In the case of either amp, I thought at those levels of THD the amp’s distortion would be buried beneath the speaker’s own distortion and the acoustics of the room.

I was also listening to Disintegration Loops the other week ("dlp 1.1" in particular) after a friend recommended it to me. Said amigo also explained that Basinski had recorded the 1.1 loop from an easy listening radio station in the early 1980s, hence the basal sweetness and dim brass remnants floating in the background.

You suggest that colouration could obscure the subtle shifts in this music, potentially rendering it boring/annoying, but I believe that an infinitely greater factor here is the listener's state of mind! The key is being at peace with oneself and one's environment and the flow of time. Then and only then can we sit back and appreciate the sheer beauty of what is unspooling before us.

On a similar tip, I'd urge you to journey with Susumu Yokota's sublime "Sakura" album and any of Mike Cooper's densely atmospheric collages on the Room40 label, but specifically "New Kiribati" and "Rayon Hula" and "Tropical Gothic".

You sound like a deep listener.

And your recommendations look really interesting. I will start with Sakura now.

peace and streaming,

Thank you for the kind words. Enjoy the music.
