Is unity gain a real HT bypass?


I'm looking at maybe purchasing an older preamp that has a unity gain setting that is meant for connecting an external processor. Does anyone know if this is a true ht bypass that avoids the preamp's processing circuitry, or will running the ht signal through this path noticeably affect the sound? The unit in question is a bat vk5i, though I'm also curious about this question in general. Thanks. -Dave

Hi Dave,

I agree with Theo that they are all similar. The tube preamp is setting the volume at the point where no gain should be added to the signal. The only way you would have a true bypass is if the Preamp would not need to be turned on and the signal would still be able to pass thru it. The only tube preamp I know of that operates this way is the Cary 2002.

Setting the preamp @ unity gain should improve the sound, otherwise there is no since in having it.

I am using a theta carmen II, theta dreadnaught, meridian 568.2 and aesthetic calypso in my home theater system. I would be happy to answer questions about the set up if you pm me.
