  2. Where we are now: The site is back up and running! The character set encoding issue has been fixed so old posts should now look ok. I am currently working on themes/skins etc and I will be deleting the temporary green skin very soon as it has many issues. I will do a very quick variation on the stock blue skin first just to get a light-grey background and san-serif font, and I will set this as default. Later this week I will hopefully add a professional third-party skin in pfm colours (life is way too short to do this crap myself, and I've found one I really like than needs next to no tweaking). We are getting there slowly...

  3. May I please request people check and update their email address if it is out if date. I ask as I’m getting countless bounce errors as the server fails to send notifications through etc. I’ll eventually figure out how to send these to a black hole somewhere, but it makes sense to address it at source as quite a few folk are obviously not getting the thread and conversations notifications they have set in their preferences.

  4. Things you need to know about the new ‘Conversations’ PM system:

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

Non balanced to balanced connetion?

    don't even know how to ask the question, well, I have Electrocompaniet PI-2 integrated amplifier which have two unbalanced and two balanced inputs.
    i have connected CD5 to one unbalanced input and Stageline to another one.
    People I trust say that thid amp sounds much better through balanced inputs, but my player did not have balanced output.

    So, would it be stupid and useless to try to connect cd player to balanced XLR input on the back of the amp?

    I'll apreciate any help on this.

    You can do it by leaving one pin floating, but sensitivity on balanced inputs is about 5volts and on non-balanced is about 2V (*generally*), so its pretty pointless as you'll have one source quieter than the other,

    0v out single-ended to 'cold' balanced, signal single-ended to 'hot' balanced. Works fine. Whether it is of value in your case is going to be a matter of experience...

    If your player does not have a balanced output, then it will make little difference whether you connected it to the balanced or the unbalanced input of your amp. In fact, it should sound marginally better connected to he unballanced input, because this probably avoids using the extra circuitry needed for balanced inputs.
