Audio Horizons TP 2.0 Preamplifier

Hi guys,
Trust most have seen the 50% off promo sale on mods being offered by Joseph.Fortunately I waited to do the "cv" upgrade,Clarity caps,Vishay resistors,harmonic re alignment(I love that term)My question is this,AH is also offering the install of line balancing out transformers for $550(ouch)and input transformers at $350,no discounts are being offered on these mods.Has anyone done this transformer mod,worth the money,consider doing both or just one and if so which one?

This new promotion is a good deal for those who have been holding back:

I am strongly considering the Vishay resistor upgrades. I already have the Claritycap MR caps in the pre outputs.

My error,the discount upgrades only apply if you purchase a new pre amp.Doh!

Oh, great! How about us poor dolts that already have an older model in need of upgrading? I know the economy's tough, Joseph. Please pass the savings on to current owners as well.

I too just found out yesterday that the discounted upgrade
is for new customers only ;o( I got excited for nothing,
oh well. I totally agree with Sherod's comment "Joseph, Please pass the savings on to the current owners as well"
Pretty please...
