| Issue with Krell KSA-250 @blakeh I listened to the video several times. Hindsight is 20/20. Shame you didn’t leave the top cover off for the video demonstration. I would have placed one hand, with finger cupped like holding a softball, and lightly touched the top of the... | |

| New Electrical Circuit @jea48 Do you normally specify isolated ground and is that why you recommend MC? @devinplombier For a residential house I never recommend an isolated ground. It would not serve any purpose what so ever. FYI even in commercial and ind... | |
| New Electrical Circuit @puffbojie The electricians have it scheduled for 15 amp circuit. My guess, the electrician you are hiring is not an audiophile. He is basing his install of a 15 amp branch circuit on bare minimum electrical code. Electrical code could care l... | |
| Interconnect Break In? A load is needed to complete a circuit for current to travel in the circuit from the source through the load back to the source. No load, no current. No current no electromagnetic fields. Does a closed circuit exist if the preamp is powered off? ... | |
| Interconnect Break In? Does the preamp need to be on? As @ozzy said there needs to be signal passing from the source to a load. Load is the Preamp in this case. Naturally the preamp would need to have the input selected for the CDP. Could the preamp be set to the inpu... | |
