I recently purchased one of these units used with the intention of modifying it to use tubes that can drive low impedances better than the 12AX7's that it uses natively.

Well, this thing sounds so darn good that I am in no hurry to change anything about it. I have the new production Mullard tubes in it and it sounds really, really good. Maybe a bit of bass bloat, but nothing serious.

Anyone else purchasing one, be a little cautious of power on sequence. The delayed turn on still allows a large thump - enough to send my amp into protection. I will look into this and see if there is a way to fix it.

Build quality is not great, but passable.

Sounds very much like my experience with Jolida gear. Excellent sound, but very dubious build quality.

You should always turn your amp on after your source components and preamp.

When you turn off your gear, always turn your amp off first.

Look it up. You run the risk of frying voice coils in your woofers by not following the proper on/off sequence, particularly if your preamp and/or amp are direct coupled. I've done this myself. Just carelessness / ignorance on my part. At least the speakers I had hooked up at the time weren't expensive and the woofers were easy to replace. Still. Lesson learned.

RDavidson: Did you read my post? The Jolida JD5T has a delayed/soft start that is advertised as such. I am fully aware of the issue and had my amp attenuated at the time. I was pointing out that an advertised feature does not prevent the problem so that some poor sucker doesn't fry their speakers.
