Biffo, I think it is horses for courses for Parsifal, you may make more headway with Karajan than with Solti. Some think Karajan erred on the side of prioritising tonal beauty, but I enjoy the performance a lot. My first choice is Kubelik, but I am not suggesting yet a third set to you when you have two.
If you have Streaming, then Abbado produced a Wagner disc which had about half an hour of Parsifal in a suite, just the orchestra, it might be a way into listening to more of it. The first time I heard it it really made me sit up. It avoids the bleeding chunks category. It also has some Tannhauser and Tristan on it.
