Owners of "Giant Killers"?


We often read of folks who have heard "Giant Killer" products: amps, preamps, digital sources...

We also often read about products that are tried, and are "excellent and worth the audition", but are not chosen for the listeners's system because of a better product.

I'm wondering how many Audiogoners actually own a "Giant Killer"?

Has someone heard a component that offers great value, but beyond the dollar value offers perfomance that has truly been good enough to replace the "Giant"?

I've never actually owned one, but the DIY version is certainly not beyond most of the folks posting here, and would be extremely economical. Here is the original, and legendary "Giant Killer" complete with some pictorial instructions, as well as documentation of proven results. Knock yourselves out!

That's high praise for the ack!Dack!, Marko445

Rar1, thanks for the PrimaLuna Prologue 2 info, as well.

I'm surprised there has been no mention of the new generation digital amps?
Marco, when did you start posing for University of Washington Life Drawing classes? You look sexy with a beard and a toga.

Marko455, the Ack! Dack! 2.0 is one of the three DACs I've been comparing and it took the bronze medal. Maybe my littler Audio Mirror D1 haad a better sling. Or a harder stone. :•)
Thanks Marko.

My giant killer is a cable -- the Sound Quest Pro Series Zero Point Reference XLR Interconnect. Fantastic neutrality and transparency (I think those are different) for next to nothing. I finally replaced them with very expensive reference cables (it took me a long while to find something better than the Sound Quests) and then changed systems which allowed me to use very inexpensive BNC 75 ohm connectors between the preamp and amps. So, I sold the reference cables but still have those Sound Quests.

As a more pricey "giant killer", the Perpetual Tech DACs (1a and 3a, the latter Wright modified, powered by a Wright power supply) are wonderful for the money. I tried other more expensive DACs and simply couldn't justify the move to a pricier system. That says a lot because, unfortunately, I'm not afraid to spend money for sonic improvements ;-) Different DAC's did present a different sound but something important always sounded worse than the Perp Techs to me. Of course, I have not yet heard some of the Giant Killer DAC's mentioned earlier in this thread. They might be "Giant Killer" killers!
