there are some postings about xcd-88 regarding its 'too brittle' sound, esp. in highs, and suggestions that replacing its opams with opa627 may possibly improve the sound (just like it does with Music Hall CD-25). Can anyone answer whether replacing opamps requires desoldering, or you just pop the old ones out and push the new ones in and. (my understanding is opa627 requires a special adapter for such an operation, but it's available from several DIY places). Of course, would like to hear the comments directly from AV123 - whether it is something which may improve the sound and if so, is it possible for av123 to create the custom version of XCD-88 with opa627? TIA.
