What's Good 5.1 pre/pre with DD, DTS, DPL II

The 20 bit has less processing power than the 24 bit. I use the 561 and had the 568 for about six months. Like yourself, 5.1 is all I required, so I saved some cash and sold the 24 bit 568 in favor of the 561. Honestly, I cannot tell a huge difference.

Bryston is a chip based software upgrade. I upgraded my SP1.7, it was $50.00 and included two chips, a chip tool, and all new case screws. It was easy.

The SP1.7 is devoid of bells and whistles, really straight forward, and downright easy to use. No video switching though!

I think the only difference between the two is the 5.1 input. I dont know about the SP1 and DPLII. I like it(DPLII) and wouldnt want to do without it, or DTS:Neo 6, for that matter. You better check with Bryston to see if those are available through chip upgrades in the SP1.

I must agree, the bryston is simple but elegant. It is more refined if that's a good term. The meridian, and I prefer this to lexicon all day, is refined but yet a great toy for geeks like myself.

Distortion: you may have had a chip upgrade done to your SP1.7, but that is not the same as having a SP1 upgraded to the 1.7 version. The upgrade from 1.0 to 1.7 is very extensive: replacement of the rear panel inputs to include 5.1 jacks for SACD/DVD-A, output jacks for 6.1 and 7.1 channel output, updated surround-sound processor formats (such as Dolby PL2), etc. The last time I checked, the cost for the conversion was $1000, plus another $200 for the newer remote.

I don't need the rear panel changed for SACD/DVD-A, also I don't need output for 6.1 and 7.1

I just want the update for DPLII.

Is it something simple standard update?

I'm goning to cantact Bryston but if anybody has any experience with it...
