Transcendent Sound Grounded Grid Preamp upgrade


I've a Transcendent Sound Grounded Grid Preamp which sounds decent, but no match for a friend's Manley Jumbo Shrimp loaned me. I understand the price difference. Has anyone tube rolled this preamp with significant improvements?
I'm running an Audio Quest AC2 power cord.

It sounds congested and not as dynamic as I had hoped. Suggestions other than buy a Manley jumbo Shrimp are appreciated. Thanks.

A component like this is built to a certain targeted price point. As a result, the cost of parts have to be closely watched. As has been mentioned above by Dan I believe higher-quality coupling capacitors would result in much bang for the buck. Get the best caps you can afford, coupling caps do matter greatly. Good luck.
