Thiel Owners

Excellent reporting- prof, ish_mail and beetlemania

very informative information for those wanting to integrate a subwoofer or two into their system. Equally important is the mention of isolation of your speakers via outriggers or some other product in kind.
Much will depend on the room, type of flooring and other sound treatments.
Fun stuff to be sure. Is not this hobby great?

Happy Listening!

I tried some Iso Acoustic Iso-Pucks under one of my Thiel 2.7s tonight.

I'm not familiar with this product but, as a rule, isolation footers should be used only for electronics and, maybe, cables but never speakers. I'm not surprised you didn't have good results.

I am using small wood blocks under the spikes of my CS2.4s but only because I am protecting the rug they sit on . . . I'm not willing to damage the rug. At some point, I will take the rug out and listen for how much, if at all, the wood blocks are degrading the SQ.

I forgot to mention what was probably the key feature in favor of the SI-1 for me. It has fully balanced circuitry, not just balanced inputs and outputs. The only other active crossover I found with this feature is a particular variant in the Marchand line, the XM44-2FBA. Since my pre and power amps both have fully balanced designs, I wasn't keen on inserting a device with unbalanced circuitry between them.

Thank you beetlemania.  I will check it out.

Good luck, bcarr38
In your previous post you wrote:

I have a pair of CS 2.3s with upgraded coax speaker which sound great but I am interested in upgrading

Was the upgrade the driver or crossover?

I am *really* happy with the CS2.4SE. It can't reproduce the left-most 2 or 3 keys on a piano but I can't hear any other weakness or shortcoming. I'm very curious to listen to a Vivid Giya or TAD Ref One or Vandy 7 again to discern how those designs are better (of course this will be confounded by changes in electronics and room). To be clear, I'm not imagining the CS2.4 is their equal but surely those speakers are near the horizontal asymptote on the performance/price graph.

have you thought about what might be the weakest link in your system? ie, consider upgrading you source or amp first? IME, these are just as important as the speaker.
