jafant, Yes I have run an All Spectral system for (20) years. All the required MIT ICs, Speaker, PCs. Currently MIT Oracle MA X.
The best cables that I have used! And they love my current system: Manley Steelhead, Pass 160.8s, Avalons. The Oracle's are hard to beat!
Yes the Spectral 4000 is a fantastic player. But I am a Vinyl Guy. (83) CDs , approaching (3000) LPs. $10,000 for a used Spectral CD is not an option. 25yr old CD connected to the (1) Manley input w/Oracle's makes CD tolerable to warmup system or listen while doing other things.
MIT has updated their line. The Oracles can be had for fair prices on the used market and well worth the price. If you can pay even the used cost. Best Wishes
