I want to add a ZMA to my collection, i can’t find the article that points out what the upgrades do for the amp and i can’t choose what if any upgrades i want.
Furthermore, i want to run it in my main system w/ my K-horns. I would be using my Vinnie Rossi L2i SE as a pre-amp to add a tiny bit of DHT300B magic to the ZMA clarity. I’m looking to squeeze every little last bit out of these K-horns. Does anyone have any experiences or knowledge good or  bad w/ this combo?
Any reason why i should NOT get the ZMA?

I’ve run the same combo w/ a 341.5 and i enjoy it very much, i want to see what the ZMA would do.

Nick324,

If you load a ZMA amp into the cart, you'll see various options available to include with your order. I for one would recommend getting all of the 25th Anniversary options and a wood base that suits your taste.

Based on discussions I had with will, a regular poster with extensive modification knowledge, I also had Steve add Decware silver RCA inputs, a Furutech IEC (model w/ built in fuse holder), and WBT speaker terminals. These non- Decware add one are not covered under the lifetime warranty. These add on were purchased from Parts Connexion.

Also, I found upgrading the IEC fuse improved the sound quality. I use a Synergistic Research Orange fuse. Anyway, that's my list and I really love this amp.

While I don't have listening experience with the K-horns, my Caintuck Audio Lii15+ speakers have similar sensitivity. The ZMA and CSP3+ preamp easily drive these speakers. Good luck.
