Did not mean to leave you hanging.<br /><br />As you may have noticed, the IVY is indeed a very good match for the opus. It sounds great. 100 ohms resistors are a good choice, though you could go lower. I would suggest 10-21R.<br /><br />Glad you got it sorted out. :)<br /><br />Cheers!<br />Russ<br /><br /></td></tr></table>2008-05-14T17:50:24-07:002008-05-14T17:50:24-07:00Russ White<table class="content postContainer" width="100%"><tr><td>Hi akione,<br /><br />Very sorry I did not get a thread notification.
