Hi Joshua
You should be fine with 270r, but too much gain may lead to higher noise floor.

That seems correct, thanks sachin. I just saw this. Today returned from travel.You will need to replace 1k resisters(R14) on Pearl to lower values like 330R to get 62db(approx)gain.

Other way is increase R15 (which in series of 100K) by additional 10K steps use that shorted jumper position Rx to add more feedback.
Thanks, Om. I re-read Pearl II article and it suggests using 300 Ohms in R14 to up the gain from 55 to 65 dB. And as suggested by you, the alternative is to remove the shorting from R15 and increase that value.
I personally kept it default gain and using SUT for my denon 103R MC cart.
Joshua, In a almost similar chain as yours, I used to turn the vol to 2 o'clock or more before I added another B1 buffer ahead of vol pot and did the 221 ohm resister mod, now I am contained at 12 o'clock or less. You could try it before buying a SUT, and even if you decide to buy one later, the above mod will bring sonic benefits anyway along with the gain.

I think you need to look other way. Please read this, may change your thoughts like me - not to get loud at 9-10'o clock position of volume pot.What's a "cheap and best" SUT? I have been wanting one but can't find one within my mental budget. I found one really good one recently but the seller is asking too much.
Actually even with the default gain, I can turn the knob of the B1 more to get the desired loudness. It's just that I need to turn it up much more than when using the Hypnotoad AD797. I mean much more.
You would be the first one here to build a DCB1 I guess, looking forward to read about.
