I had the Titan i for 6 months in my system, and my friend Richard has the Olympos in a very different system so I really can't give you a valid side by side comparison. In my opinion, Doug is being very generous to the Titan i. I found it cold and clinical in my system especially after running the Lyra Helikon for 2 years. My biggest complaint with the Titan i however, was the complete lack of emotional involvement it was able to transmit. The Olympos did not suffer with this ailment........whether it is the equal of the ZYX Universe?.....well again I think Doug is being a little generous. But then, he is far more qualified than I to formulate a judgement.
