Bybee Internal Speaker Bullets - user feedback?

I added a couple of Bybee Small Slipstream Purifiers on the RCA inputs in my amp and like the effect quite a bit.

Exchanging with Jack Bybee, he said the internal speaker bullets are, in his view, the best bang for buck of his products. That would be an expensive move for me as I would need 2 sets (they retail at about $800 per set).

Searching around A'gon, I was surprised to see little talk about these. Found a thread from 2008 discussing the Bybee Golden Goddess that apparently had just come out at the time. I believe the Internal Speaker Bullets are a DIY version of the Golden Goddess, that retails at $4200 (!!).

Would love to hear from those who tried them. In what kind of speakers? Was it worth it to you?

My speakers are B&W 804S. They were $4k when new...not anymore. I have to wonder if best bang for buck is to spend $1.6k on these Bybees or upgrade the speakers. The Bybees I can keep with me in future speaker upgrades, though.

Thank you!

Lewinskih01,

I would start treating the AC inlet of your source components since it will have the greatest impact IMHO. My first Bybee mod was performed on the AC input of my Benchmark DAC 1 and it litterally transformed the unit. Impact was so good that I did the same mod on a second Benchmark DAC I recently purchased.

My second mod was on the AC input of my Krell FBP 350 MCX monoblocks. Again, same increase in resolution. Last mod was performed on my refurbished Apogee Duetta Signature ribbon speakers done by Rich Murry. Rich has replaced all the ribbons and I have rebuilt the Xover from scratch. This is when I decided to add the Bybee speaker bullets on my external Xover. Again same incremental effect of added resolution.

Be careful if you want to install the Bybee on the analog path. I have looked into this for the Benchmark and Krells and the operation was too risky because of lack of space to install these. Maybe your gear will permit it or not. Best bang for the buck would be to do the AC path since far easier to install. Personally, I would not be putting $1.6K on a $4K speaker as your first step. Start installing Bybees upstream in your system and going downstream afterwards as money is available.

I have seen the inside of one of these "purifiers".
There's nothing inside! Just a ceramic tube with a little caked clay inside.

Well, that's High End.
It's a product for "Audiophiles" with more money than brain.

Good way to invalidate any warranty and I do know many manufacturers will not repair equipment modified by owners. Also on resale who wants equipment modified by owner with no manufacturer support?

Audiophiles invalidating warranties? Don't be silly.

I have used various types of Bybees over the years in electronics and speakers. I still use some in electronics, but I've found that in speakers they do improve the soundstage, but seem to reduce the top end a bit as well. Net, I like them with some speakers, not with others. The price/benefit ratio has gotten out of whack, though, IMO.
