Analysis Plus Oval 9 or DH Labs T-14?

I am looking for a nice speaker cable upgrade at a reasonable price. I have heard great things about the Analysis Plus Oval 9. Any opinions?

Currently I would characterize my system as being on the lean side. When playing Diana Krall I have no complaints. But on very dynamic material, my system can get strained and sometimes tizzy. I would favor a rounder, warmer sound without sacrificing too much detail if possible. I currently have a system comprised of the following:

Sim Audio Moon I-5 integrated amp
Musical Fidelity Electra E60 CD player
Sonus Faber Concertino speakers
NHT SW3P subwoofer
Cardas Golden Cross interconnect [CD to amp]
DH Labs Silver Pulse interconnect [amp to sub]
DH Labs Silversonic T-14 speaker cable

I am in the process of purchasing a Sony SCD-777ES. Hopefully, that will negate the possiblity of my source being the problem. I have also thought of replacing the Sim Audio with Blue Circle BC21 preamp and BC22 amp. But I really like the Moon I-5 and before taking that step I'd like to see if speaker cables can do the trick.

This "problem" was much worse until I switched in the Cardas Golden Cross in place of the DH Labs BL-1 I was initially using. The Golden Cross is affordable as an interconnect but becomes a very expensive upgrade as a speaker cable.

Any ideas?
