Is no preamp really better that a good preamp?

Andrew9405, you crack me up!

Thanks for asking, George. I have the PS Audio DirectStream DAC and their Memory Transport CD unit. I also have their Phono converter phono section. I really appreciate the help; I'm not really close to any place where it's easy to audition stuff, so all the advance advice I get is greatly appreciated.

I also use a Spectron Musician ii high current power amp to drive Martin Logan Spires.

Hi Rustler.

Your PS Dac has from it's single ended output has 100ohms output impedance at 2.8v from it's "Resolution perfect volume and balance controls"

Your Spectron amp has 50kohm input impedance at 26db of gain.

These are a perfect match for each other to go direct with, and will give you the best transparent/dynamic sound you can get.
By putting a preamp into the mix you are just throwing money away to colour the sound with.

Cheers George

Like many people, I tried to save money and eliminate the preamp. If you're happy with what you hear without it, then good for you. Ultimately I opted for a preamp. I can't remember which Sterophile writer said that "the preamplifier is the beating heart of a system" I fully agree. I'm using a Classe CP700. I can't imagine doing without it.
