Isolation Transformer and Subpanel recommendations

There are many isolation transformers out there new and used. What are the best recommended 5kVA/other isolation transformers for high-end audio setups. I live in the US so I need one that would be configurable for 110/120V output. I intend to put this on my dedicated circuit after my main panel in the house. The dedicated circuit is high-quality and 20-amp/10-guage in nature; this circuit is 110/120V, not 220. I'm looking for any recommendations for units that run quiet and have high common-mode noise rejection.

Also looking for recommendations on good quality sub-panels.

Thank you in advance for the assistance!

Plitron transformers perhaps or even the Torus site.

I sent you a message via the new audiogon messaging system. Hopefully it works.

Quick search on Ebay turned up empty for this size and 120V. Generally prefer iron core instead of wide-band toroidal for this purpose. If it's going to be close to the rest of the system, toroidal has the benefits of less stray EM and more convenient packaging. Without step-down....

Although, if you can get 240V there, options get much wider and less expensive. Perhaps even the option of center-tapping, if derated by half.

Thank you for the help and pointer; we can get 240V here up to the house but given it's US, it has to be broken into 2 120V phases inside the house. I'll check out the link you sent.....thanks!
