Audio Horizons TP 2.0 Preamplifier

Slttrains - congrats on a good decision in a complex obsession prone enviroment:) I am very happy for your excellent synergy among your pieces of equipment. It is so healing to be able to sit back and let the music transport you to wonderland. Bill, I also have the house to myself tonight and tommorrow. Wife is taking second daughter on a tour of possible colleges. Listening to Bach tonight and marveling the night away.

Sherod, Wow your a man of action! Seems you got down to the bottom line on the upgrade and burn -in. Not so much the wire harness or power supply, rather its the output caps and bypasses that are troubling you.

That is great to know Sherod, but one important question still remains for this audionut. Would the caps you've removed ever have settled in and actually sounded better than the ones you put back in? Vic and Joe sure think they did?

Just reading this thread we know other caps took upwards of 350 hours and changed quite a lot over that time.

I am curious what your thoughts are on this.

One other question, I hope someone can help me with this. Tube positions 1 and 3 are where? Looking at the front of the unit and starting from the right hand side?

Stayed up to 3:00 AM listening. Music always sounds better after midnight and what's with that folks!

Thanks,

Bill

Bill,
I think 140 hours on my upgrade was enough break-in for me to know if the caps were right for my system. Regarding the tube locations. Looking down from the front, starting from left to right is location 1-4. 1 and 3 are the most critical to the sound. I might be up to the wee hours myself listening this weekend. The fun is back. Enjoy.

Grant,
I agree that Blackgate caps take an unusually lengthy time to break in. Some have said the larger values take up to 600 hours or more. Most of your polyprops, metal films, oil impregnated, etc. take much less time. Speaking of Blackgates, I have read that the manufacturer has stopped making them. I know that Joseph uses them in some of his tuner mods. He put some in my tuner mod.
