James,
I was going to PM you on this question but I thought others may also be interested in your response.



I did a search and confirmed what I thought, that the 14Bst and 14Bsst are basically the same except for the extra 100wpc output.

As far as sound goes, they are identical?

Can you do a factory upgrade for a 14Bst to a 14Bsst?

If so what would the cost be?

Would the factory upgrade change the warranty (sorry for using that dirty word   ), stay the same or extend it?

Performance wise, what would you say about the 14Bst vs 14Bsst with my OB1's?

Thanks,
Tom

Dear Tom,

I'm not James but feel to answer

For so far I know, the only difference is a slightly higher voltage rail for the 14BSST.  That gives the SST version a little bit more output power. To get the same voltage rail in the ST you have to replace both transformers. Personally I don't think that it is woth al the effort and money. more then 500 watt's in to 8 Ohm is still more then you ever need. If the V/A rating of the ST transformers is the same as the SST the ST can even deliver more current into low impedances because of the lower voltage. voltage times current is power (U*I=P). If the V/A rating from the tranformers is the same but the voltage is lower, the current wi be higher

Like I always said. If it sounds good it is gooD and don't change a thing!

Best regards,
Bas

Hi,

Yes the transformer in the SST is slightly larger and amounts to about a 5% increase in power.

I agree with Bas --- not worth doing.

Bas,

Thanks very much for your input.
You are right, who really needs any more that 500 wpc.
Hold on a second... why is James building that bloody 28B.
Oh ya, cause he can.  

My main concern is really how they compare, sonically.

James,

Thanks for the confirmation on Bas's post.

What brings this topic up for me is that I have a chance to pick-up a
14Bst at what seems like a pretty good price.
If all things are equal, other than the extra output, that's fine with me.
But if I might be missing something sonically, I would rather hold out for a SST.
I was very pleased when I heard OB1's with a 14Bsst and I want to make sure that I get the same result with a ST.

Hi Tom,

I do not think you would give up any performance going with the used 14ST.

I know this is a bit off-topic, but could you knowledgable types perhaps tell me the difference between a 7B ST and a 7B SST?

Dear docter Doug,

-Faster powersupply (16 fast elco's close to the output devices on the amplifier module) In the ST it were 8 elco's in the middle of the chassis
-2 times higher elco's capacitance
-Faster and more linear output devices
-New grounding design
-Bigger powertransformer

Most important the diference in sound. The SST have better highs and sounds darker and more natrual. The top high are really a big step forward in my opinion. The old 7BST have a nice sound of it's own with some "bite" However the new 7BSST is a amp that really dissapear in the soundfield. The amps is always natrual and not recognizeable anymore in the system.

The old 7BST can sound a little bit thin or harsch in some cases. The new 7BSST is one and al blackness and harmonicly totally right! That's why I love them so much

Best regards,
Bas

Hey Doug,

Actually, your question is right on topic.
Thanks for jumping in.

Bas,

That is exactly why I was asking my original question.
I want to make sure the 14Bst has that same sound signature as opposed to the 7Bst, as you described.

From all reports the 14Bst should sound like all the current sst's?

Thanks, I appreciate your input.

Dear HP power,

So far as I know the 14BST was on of the first SST design's. With the SST groundschematic, the SST outputdevices and SST topologie. So it is a real SST design with the SST sound signature. I can confirm that myself because I listen a lot to the 14BST when it came out first. And it is the kind of (SST) sound as I described above. Lateron Bryston want to upgrade the whole line of amplifers with this new topologie so they called them SST. To make the line complete the 14BST also get the "SST" behind his nameplate and they raise the power a little bit by raising up the voltagerails a little bit.

Mebey James Tanner can fill in to confirm to make you feel confort with your 14BST

Best regards,
Bas

I could not have said it better.

Thanks guys,

Please pardon the pun... That is what I wanted to hear.
