Also, can you explain briefly the differences between an isolation transformer and power conditioner as used here for audio gear? In other words, which type will benefit the CS more?

Here are my two examples:

Tripp-Lite IS250

Tripp-Lite LC1200

the first one will provide better sound from the cs. the second one will protect the cs from damage. i really wouldn't worry about damage unless you get brownouts and surges all the time where you are at. at those prices you will not get full line isolation(online ups). you don't need that for the cs either. i'd pick the first one.

Thanks for taking the time to look at the units. I will get the isolation transformer then. I do get lots of thunderstorms in the summer with at least a once per week power outage which I'm guessing leads to surges.

One last question (no promises ): You may have answered this already since I've been on this subject before...but, can I safely plug my Tripp-Lite IsoBar 4Ultra into the isolation transformer - or would this not be beneficial?

There are 3 other components that I think should get the same treatment...tube amp, CDP & processor. If using the IsoBar is a no-no with the isolation transformer I will plan to use a good quality 6~8 outlet power strip instead.

you should never "daisy chain" electrical protection devices. these devices depend on a clean ground being present. plugging the isobar into the transformer makes the ground path longer. that is not the real problem though it is the blades in the nema socket lessening the grounding area. just plug the component you want to protect directly into the transformer.

Thanks again. I have another use for the IsoBar but just wanted to be sure.

does anyone know if the channel islands vda-2 and vhp-2 together outperform the cs by a large margin?

If money were not the issue, can't you bypass the head amp in the DAC 1 and use an external tube headphone amp like the Bada PH12 or DOGE 6210? Woun't the addition of the external tube amp warm up the analytical sound of the DAC 1 with the AKG 701???

The DAC 1 seems to have the best error correction and plug and play compatibility with the Mac for playing itunes library in lossless.

can you give examples of tube "balanced" headphone amps?

Thanks for keeping us updated on your experience with the Presonus CS Music Man. I too am looking for a tube somewhere in the CS.

If anyone can suggest some good RCA cables for this I am all ears. If not some other adaptors than the units sold at Guitar Center.

I bought these and have seen them suggested elsewhere: http://www.sweetwater.com/store/detail/DKQR3/

I bought a pair of IC's from bluejeans cables for my presonus. No complaints here.
post #116 of 145
I have purchased both Pro Co (from Sweetwater), and BJC IC's, and I am happy with both. I am not sure there is much of a difference in sound, but the BJC IC's look and feel like a more substantial, albeit less flexible.

I'm using Mogami Gold TRS for a balanced connection between my CS and Aphex 204. I've considered buying the Mogami TS>RCA here which isn't bad for $17 but 6' is too long and I'd rather have Blue Jeans in custom length. I'm waiting for a price quote for an order.

Those Pro Co look like a good deal too.

Has anyone compared the CS's headphone amp to the Presonus HP4?
post #119 of 145
In the older Presonus threads here (you can find them if you do a search), it is almost universally agreed that the Central Station's amp is better than the HP4 (probably due to better power supply).

-edit- i'm considering doing a little bit of modding on the CS. I'm not sure if I'm just going to replace the power supply section with better quality components or if I'm going to get a little crazier and try to fit a zapfilter in there. Maybe I'll pop it open again tomorrow and take some close up pics and post over in the DIY forum for some suggestions.

Can the Central Station be used with a Mac computer to output iTunes files via Toslink?
