If the Dyna-70 Ultimate Upgrade itself is not enough to satisfy your quest for the best sounding ST-70, we offer the following items to further improve and expand the high-fidelity performance qualities of your Dyna-70 upgraded ST-70. This involves component replacements, where we have taken the extra time & effort to hand match components for use in both left and right channel circuits of the Dyna-70 PCB, increasing the probability of your hearing and capturing those subtle, background musical nuances, whisps of human voices, missed notes, out of rhythm bars, etc. As we play familiar old recordings, we discover new sounds all the time; minuet notes we have not heard before, or so long ago we forgot about them. Next, we bet you will find you need better recordings because you will hear more “junk” also, LP’s being one the best examples of poor recordings made back in the ’70’s. It is what makes us all Audiophiles!

Available for our stock Audyn, Mundorf or Solen Polypropylene film capacitors. You pay the regular price for the caps; however, we charge a flat fee of $30 for a matched set of 6 film capacitors ($5 per capacitor). This involves someone grabbing a bunch of caps and measuring them all, then culling caps in groups to make matched sets. Not hard to do with the 2, C8 film caps, but harder to do with 4, C9/10 caps, requiring a much larger set of caps to start with.

NOTE: If you wish to incorporate this upgrade after purchasing a Dyna-70 Ultimate Upgrade kit, just send us back the supplied film caps and we will exchange at no cost for the caps. This assumes you purchased a standard kit equipped with Audyn film caps. You can also “trade” your new Audyn caps in (must be new, un-used and returned in same condition as received), and we give you full retail credit towards Solen or Mundorf caps upgrade, you just pay the difference in cap price, plus the $35 matching labor charge, as well as shipping and handling.
