Are there passive attenuators that don't zero volume and only offer one input ?

If you want to use LDR's , as I observe in other designs, they find it easy to both achieve silence at zero volume, and to also have as many inputs, as are required.  

True but it's not as pure a signal path. I have owned my LDR passive (Lightspeed) for over 10 years. I have also built/owned other resistor and transformer based passives. The simplicity of the Lightspeed and the ability for it to stay out of the way more so than the other passives is why it is the one that stays in my system.

Back to the topic, who agrees passives should be able to zero volume and have more than one input.

These are trivial features and not important to me. What is important is that the passive preamp is well designed and gets out of the way. If in doing so it can zero volume and have more that one input fine, if not that is fine too.

As I stated previously I have had many passive preamps in my system. Some zero volume and have multiple inputs, some were made by manufacturers and some I DIYed. In the end the Lightspeed Attenuator which doesn't zero volume and has only one input is the one that I keep coming back to. One of the best bargains in audio and one of the best purchases I have ever made.

@dbxrecord who cares. This has been a pretty useless thread. You are obviously trying to take a poke at another manufacturer's product with the hope you will get gobs of people to agree with your point of view while pimping your products feature set. Obviously it's not happening so give it a rest. People can make whatever decision they need to regarding the features they desire in an LDR preamp, or any preamp for that matter. I've made mine and I'm not looking back.
