I went down a similar path recently. I had a Jolida JD9 for years, and was pretty happy with it mated to my Primaluna HP integrated. When I got my 10x5, it became more obvious that the preamp is a little noisy with everything else I have.
Here is what I auditioned:
-Musical Surroundings Nova II - had it for about 6 months. Found it to be smooth, warm, and quiet. But, rolled off at the high end. $1200
-Lehmann Black Cube - sweet, but laid-back bass; clear highs, a bit lean in the midrange $1k
- JD9 - had it for 6 years. Fully upgraded. Nice, warm tube sound, but clean and clear overall. Some "fuzzy" around vocals which I think can be typical of 12AX7. Vocals a little forward. $900
- Project TubeBox DS2 - auditioned next to PhonoBox RS. This is a nice tube preamp, but not much different than the JD9. It has a nice, sweet overall sound, good bass, clear highs, but it's a little noisy. It's a lower end tube phono, and performs well in that space. $750
- EAR834 - considered but didn't audition, because as you say it's all about the mods. Having done that with the JD9, I don't want to go down that rabbit hole again. Get one that's good out of the box.
- Decware - I briefly considered, but it seems like everyone ends up waiting a very long time for them to deliver. I am impatient, and cannot wait months.
- Project PhonoBox RS - liked it a lot. Bought it and had it for three months. It's quiet, smooth, great bass, clear highs, nice midrange. But, after having the demo a few months, then getting a new one and returning the demo, I decided it wasn't enough of a step up from the JD9. I paid $1k, and would sell for less (see the classified ads on 'gon). Let me know if interested... it only has about 10 to 15 hours on it.
- Finally bit the bullet, and went for the Manley Chinook. This one is a major step up. It's still breaking in, but I can tell it's more musical, taut bass, sweet vocals and great highs. It's what I've been looking for. $2400.
You said the budget is $1500-$2k, which is the same as my budget. I think that's a good budget to match with the 10x5. I was able to find a Chinook under the $2k mark, and I think that's a fair price. You have good recommendations above, but many are double your budget. I suggest you consider a used Chinook, in your budget, or you can buy my RS, which is very good for under a grand. :-)
Happy hunting, hope my notes are helpful!
