I told you God Particle should be an obstacle test course for any recently completed WOPL amplifier. If it can handle that, it can handle anything.

Well the Coherence is a helluva pre so the fact the modded Acurus is in the same ballpark as it is a good thing to hear. I'm really partial to the Acurus pre's for the price the build quality and design are hard to beat.

125 - 129dB RANGE!!!
WTH man you are close to breaking windows. :)

Yep, damn close....
Yeah, I'm getting pretty attached to that Coherence....

Thanks Lee. I ordered one off of AudioMart, arriving today. I surely will look into the upgrade but wanna hear it stock first. Most of the parts swaps looks like something I could handle, cept those custom tiny boards.....................

Put her thru some paces last night. Pretty good sounding stock. I think I will leave it in long enough to make some small upgrades to the Yamaha pre that I've been running then pull the Acurus for the full monty that you had done to yours Lee. I'll see if Mondialfan might sell me some of those little PCB's so I can do the upgrade myself. Looking like the Acurus will be a keeper for sure. Cheap and good, my favorite!

I have a stock RL-11 Scott, none better...had one of those expensive Accuphase pre's for a while, the Acurus smokes it.

Yeah, I had the C-200 as well and I recapped it but it wasn't anything to write home about. I have had a number of preamps in my time, Pioneer C20, Spec 1, Horneshop The Truth, Harmon Kardon, Denon, and more. I've found Yamaha to be my favorite by far, now this Acurus is on par, could be better but it is close. If upgrades are like Lee is hearing, I could be done on the SS side. Still wanna try a tube pre with a WOPL yet.

I bought an"as is" Acurus integrated something or other at a flea market about 10 years ago for a negotiated price of $5. It had a blown fuse. Traded it for a working Marantz 2275. Never really played the Acurus. Liked the hybrid design though. I lusted for the Marantz since the mid 70's.

The C-200 colored the music a lot, it sounded OK but artificial.

I haven't been on the forum in a while but read thru this thread and thought I'd mention that I have an RL11 that Kevin upgraded a few years ago. He outfitted mine with an outboard power supply and I've told many people that it's likely the LAST piece of audio gear that I'd ever sell. I've swapped in other preamps here and there and always come back to my modded RL11.
If I'm not mistaken, the guy Kevin originally built it for tried to buy it back a year or 2 ago. Kevin would likely remember better than me. I've got another RL in the box, just in case! I'm feeding my Aragon 8008bb amps with this thing. I think the Acurus power supplies and the 10V+ output just man-handles whatever you have. Love it!!!
