I'm just putting together a system and will be driving fairly high efficiency speakers (probably Axioms or PSB Images, both rated sensitivity >92 dB) and will have a CDP, tuner and turntable. I'm looking seriously at a couple of Stealth 5 amps.
Can someone suggest how to choose between these two preamps? I know that, vis-a-vis the Ultra 4, the Octal 6 has the three config choices, built in power supply and no phono stage.
If I do the math right, a pre-assembled Octal 6 + a Phono 4 will cost $200 more than an Ultra 4m + a PS 1m power supply. What would be gained for the ~33% price differential? Re the Ultra 4, is there a significant benefit to having the power supply separate from the rest of the preamp?
Many thanks.
