Famaraca - I also have the Helikon SL and think it's terrific, better than my Koetsu Urushi, and gives my Koetsu Onyx a run for the money. You have a high quality tt (SME IV/V arm?), so the just be sure your phono pre has enough gain to support the SL.
And Gboren, I'd stick to the regular Helikon with your Linto, but you might want to email Sedrick Harris, Immedia sales rep to confirm (immediasales1@comcast.net). Sedrick's a great guy and very knowledgeable.
To both Famaraca and Gboren, a friend upgraded his Lyra through an Audiogon member, Sattothestars, and was very happy with the service.
