Anybody tried a linear psu with the liquid platinum, I keep reading on some places that states its sort of dangerous to use with the LP can someone confirm
Not sure a linear PSU is needEd with this amp. Changing tubes nets you bigger sonic gains. Having the cap mod done totally transforms the LP.

They were talking about it here yesterday; you can find the info on the previous page. Sounds intriguing.
Thanks!

Dang! I just read about that cap mod, and it sounds like a killer upgrade. I would love to have this mod done to my LP. @ksorota , I sent you a pm. Thanks!

@Wes S the sound is unbelievable. The LP is a totally different sounding and performing amp now. I'm still trying to wrap my head around how a small upgrade can bring about such improved sound without a redesign. But as I'm sitting here listening to the LP with my Susvara's, there is no denying the sonic benefits that upgrading the caps has brought to the table.

It's been asked but not answered: what's the total cost of the cap mod? (Frankly, just curiosity. The chances I would do this to my LP are pretty much zero regardless of cost.)

Someone who got the mod done told me it was $150 total, parts labor and return shipping included.
Thanks!

That's awesome! I am getting it done, and have already got in touch with the man. I can't wait to hear it, after the cap swap.

Having worked for years for a well know mod company, YES it will void your Monoprice 5 year warranty. Heck at the cost of a new LP if it dies, spend the $150 and get a better amp TODAY. Life is full of risks but the LP has been pretty reliable and why not get a better performing amp?

$150 shipped seems reasonable to me.

Just wanted to confirm a few things regarding the capacitor swap.

First of all, thank you to all who have reached out already...I have never had so many pm's in my inbox and I really appreciate all the interest.

The mod for sure would void the warranty but in my opinion is a pretty low risk modification. I am replacing 6 total capacitors on the board and the board is pretty well spaced out almost appears to have been designed to use larger caps.

I am asking for $150 to do the upgrade. This includes the cost of materials, the swap and return shipping via USPS (insured). The swap can be done in an evening, but with my career work picking up I am going to say that 2 days should be expected. If I have a lot of interest then it may slow down the turn around time, but that can be discussed on a one on one basis.

I make sure to test each of the capacitors prior to the installation to make sure that they meet the specifications and match each other within a few points.

I am using Elna Silmic II caps, but if someone wanted another brand (nichigon, rubycon, etc.) I could change those out as well.

Lastly, solder work is something that I have become proficient at through my career work and the audio upgrades/repairs that I have been doing lately are fun to me and good extension of the hobby. That being said, I apologize for any delay in response to questions or updates to gear, but will do my best!

All the best,
Keith
