biamping with 75 watt solid state and 18 watt tube amp.klipsch rp600m...t

@jayctoy,
Thank you for your reply and additional detail. It seems that the Klipsch can be an exceptionally good sounding speaker when paired with properly chosen components and cables. I suspect It will sound truly captivating and engaging matched with your  Viva 300b amplifier.

@jayctoy,
You find the Klipsch sonically competitive with Omega speakers? Many would interpret this as high praise. Omegas are noted particularly for purity of tone and coherence. Do the Klipsch compare favorably in this regard?

I know that you have a tube amplifier (Line Magnetic I believe) have you used it paired with your Klipsch? There seem to be two opposing opinions of Klipsch expessed frequently on this forum.
1. Too bright, edgy and forward, i.e.ear fatiguing.
2 Very good lively and engaging/ involving sound quality especially if used with a good tube amplifier.
