Audio Horizons TP 2.0 Preamplifier

I'd like to know what Joseph charges for this mod to accommodate such a low output cap. The original TP 2.0 has a 4.7uf cap. Too low a value can raise the bass roll-off too much. I experimented with lower value caps in my TP 2.0 preamp and they just didn't sound right. I understand that this output cap is very important. I found the original Hovland and the Claritycap MR to sound the best. I would imagine that the V-Cap copper would be the best sounding of the lot, but like you said, they are very expensive and if a lower value can be used, then I'd like to know how.
I have been experimenting with electrolytic caps in my tuner power supply. The previous modder had Panasonic FC caps in there, an upgrade from the originals, but when I replaced those with Elna Silmic II caps, the sound improved greatly. I'm thinking about doing this in my preamp power supply.

I can't remember what the cap upgrade cost. It was done in conjunction with other upgrades including a new wiring harness etc.

Best to email Victor for a price quote.

I will say it has been my experience that Joseph's labor costs are very reasonable in all respects.

Scifi,

Thanks -- in the process.

I made some cable changes recently -- added David Elrod. Now the Siemens Cca are the perfect pair in positions 1 and 3.

A while back Gammajo mentioned loading the TP with bookends. For years I have done bottom loading of all components and speakers with sand boxes -- Tupperware-style containers filled with dry beach sand. I just tried top loading the TP with a single container (about 5 lbs. of sand). The sound seems to improve. Two containers make the sound diffuse. I just tried top loading my transport. Seems like more improvement. Has anyone else tried loading with their TP system?

Has anyone tried Siemens E188CC in positions 2 and 4?
