Spectral preamps


I've read that Spectral AMPS must be used with Spectral preamps and MIT interconnects and speaker cables.

Does the same rule apply to Spectral PREAMPS? Can they be used on their own with other manufacturers' amps?

I assume the same rule applies for amps and preamps, but just checking. Thanks in advance.

Spectral is to be used in a complete system. You really have to go all or none.

I was going to try a Spectral preamp as well---but its just not an optimal setup without the amps.

There are benefits to this---but the big problem is if you decide to change routes, your entire system has to be put up for sale.

As far as sound---its whitish to me and sterile as an entire system. That is why I was hoping just a preamp could be a great solution.
>>> "This, to me, was a product, after having been so anxious to hear it left me very disappointed...to the point of wondering what 'all the shoutin' was about.' For those fans of Spectral, is there some magic combination of equipment that shows off what Spectral can do? "

Yes and it includes high quality speakers - w/o a reference to what you heard we fans can't be really sure why you heard what you heard. So, for example, if you are used to speakers which tend to emphasize treble because they are meant to be paired with amps that roll-off highs (perhaps because the amps can't get the highs right), then switching to electronics that can get the treble right may sound too bright, and rightly so.

So when anyone says I heard X COMPONENT and the sound was such and such, there really is not enough context around it to say anything. Suggest you also discuss this at the [unofficial] Spectral forum at http://whatsbestforum.com
I just switched from an Nagra preamp and am to Spectral 30ss and 260 amp. More transparent and I can hear small changes in cable/source. Not standard solid state. Very liquid, open, defined stage. I'm very happy with the change.
Here is the technical reason why Spectral electronics MUST be used with MIT cables:
Spectral's designers believe that for best sound, amps and preamps must be able to pass ultra-wide bandwidth, in the Mega Hertz range.
Their preamps have no RFI filters and their power amps have no filter (zobel) networks at the output, therefore, Spectral gear depends on outside filters to be unconditionally stable, hence the recommendation to use MIT cables.
MIT cables include "networks" at both ends, these are actually RFI filters, which prevent oscillation and filter out-of-band noise.
In summary, anyone who chooses to ignore Spectral's recommendation is doing so at his own (and hist tweeter's) risk.
Enjoy the music!
Casouza,
To amplify, no pun there, I have a story about MIT Cables which bears repeating.
Years ago, and I mean YEARS, when Bruce Brisson and Karen Sumner partnered in distributing the MIT cables, they quickly, because of her marketing genius, became very well regarded by the press AND the consumers out there.
I have to say that, at that time I tried them, even sold them for a while, as I had a connection with Ms. Sumner (later of Electrocompaniet).
Soon after my initial blush with the product, I became convinced that there was something 'tonally' about the cable that I didn't agree with. Then after long sessions, comparisons etc. it became 'apparent' to my ear that the cables were 'rolled off' on the high end and, to my ear, 'lumpy' and forward in the bass somehow.
After a cocktail reception at my store, Jim Thiel and Karen Sumner and I went to dinner. It was quite the evening...thank God for red wine.
After quite a bit of silence (uncomfortably so)by Jim Thiel, he finally confessed to the table, "I don't know what Bruce Brisson is talking about." Saying it in that quiet and sincere voice that only Jim had...yet with an authority and surety that only he could present.
"He's not practicing any Newtonian physics I've ever studied, so I'm confused at how he decides what to do, OR how he's doing it." One of Jim's basic complaints was that the cables was (this is a 25 year old memory, but presented honestly)that the cables were 'highly capicative', rolling off the higher frequencies, acting like a capacitor in line.
OK, that was 25 years ago, and everything, everyone, every product evolves over time, no doubt. As I recall, Karen Sumner and Bruce, disolved their relationship, which may only be faulty memory.
I do know this, and the point of this windy story is, that I've always suspected that the MIT Cables were coupled with the Spectral to 'mask' what I guessed was not just full bandwidth delivery, but a 'forward' high end on their products. Let's face it the 'problems' that I believe I'm hearing, are not in the Megahertz region, but octaves below that--and effect the harmonics of some mid range data.
I haven't heard the Spectral in the past couple of years, to be fair--so tell me I'm wrong, I'll believe it. Yet, the 'house sound' usually is a constant. If not, I'll give way to someone with more current info.

I have great respect for well engineered products, but could never warm up to the Spectral. BTW, Spectral is not the only product to present ultra-wide bandwidth information, so I'd like to hear from someone who's more informed about their designs.
I'm completely open to a new way of thinking about Spectral.

Thanks,
Larry
