Hi, dear Mega, nice to meet you. I am new to this forum, I am very happy to meet someone who hv used the Gryphon Mirage, colosseum and playback. I see we have very similar taste because those items are all in my consideration list. Actually I like you speaker very much too but I have chosen the Rockport Alya at the end because of my listening area and I dont listen to classicial very often. I am thinking to upgrade my amp and source. And I am now comparing the Jeff Rowland criterion/625 to the Gryphon Mirage/ Colosseum and Playback to XDS1 to KO-1, XDS1, TSD1/DAC2. I am very looking forward to have your advise, thank you very much. PS: hi to everyone too
