It seems only right for my 250th post that I do it here in my home, the 2 channel forum. I love my SDA's!!!
That's all, you can go about your business now.

Congrats on 250.....now tell us more about your SDA's....:cool:Oh, the bottle has been to me, my closes friend, my worse enemy!

Thank you!
I've got some 2B's (not in use) and 2.3TL's, same as you. What more do you want to know. Political Correctness'.........defined

Ok, they are big, bad and beautiful. I thought I was going to drop a nut getting them into the house and the effing cat attacked the right side panel of the right speaker.....anybody want a cat?
Actually I've got the cat sorted out, I placed a golf ball sized pink and black soccer ball in front of the injuried speaker. I don't know why, but the cat is terrified of that little ball and will not go anywhere near it...works everytime!
Back to the speakers, about the only thing I need now is more power.....mono blocks, when I can find some time for shopping.Political Correctness'.........defined

My sister has 4 cats and when I was home taking care of my Father, who is now deceased, her cats would use my SRS's at a clawing post. Arhh. Had fun with the grills. BTW two channel SACD sounds nice on these clasic speakers.

Need more power?

My personal quest is to save to world of bad audio, one thread at a time. -
I have my vintage 1998 Sony ES TA-N77ES amp & TA-E77ESD pre.
It's about 200 wpc and it drives them ok, but I'm thinking mono blocks. I plan on testing a Conrad-Johnson 17LS pre with a pair of Bryston 7B-ST amps at 500 w each. The idea I had was that the tubes in the pre would mellow the SS amps. Any thoughts/opinions are welcome.Political Correctness'.........defined

Oh ya......7B-ST Monoblock
The 7B ST power amplifier is of the bi-monaural construction. It means that everything, which handles the analog signal, is totally separate for each channel (two power transformers, two rectifiers, independent capacitors). Why is everything doubled in the monaural amplifier? I will explain later.
If the amplifier does not have separate power transformers, it is not dual-mono, as is often quoted i.e. on Sony or as my colleague **** wrote in the Accuphase P450 review. Bi-monaural is not also the amplifier with the separate secondary windings on the power transformer.
It is important to emphasize the advantages of the hi-monaural construction. When the audio signal is reproduced, the power output modulates the DC voltage of the power supply. If the power supply is common for both channels, this modulation is transferred to the other channel and vice versa. The result is higher cross-talk and subsequent deterioration of the localization of the sound images. A bit better solution is the aforementioned use of separate transformer windings for each channel. You can easily recognize this type of amplifier by two pairs of capacitors and two rectifiers in the power supply. If the amplifier has only two power supply capacitors, you cannot speak about bi-monaural construction at all (P-450).
Bryston 7B-ST is a monaural amplifier, which enables two modes of usage. The first one is described by the manufacturer as Serial, which is only a different description of the usual bridged configuration. In this mode, the two amplifier sections are driven by the signal in opposite phase and the load (speaker) is connected between them. The second mode, Parallel, enables the paralleling of both modules for much higher current delivery. It means that the amplifier will be able to work into substantially lower load impedance.
7B-ST is basically the modification of the already tested 4B-ST. The major difference is, that it is permanently connected for mono operation (serial or parallel, see above). The second pair of input terminals on the back is therefore missing. The input is switchable for non-symmetrical (gold plated RCA) or symmetrical (XLR/Jack - Neutrik) connection. The outputs are five way binding posts with gold plated contacts. Between them is the isolation ridge which prevents the short-circuit by bare wire. Nice touch. The power cord is three-prong, the component therefore works in Safety Class I. But, it is possible to disconnect the working ground of the amplifier from the chassis using the switch on the back. The ground is not disconnected completely, but through the 10 Ohm resistor, which is sufficient for the elimination of ground loops possible when connected to other equipment working in the Class I. Using the usual "cheater" plug is much more dangerous.
The amplifier modules, placed vertically on their heat-sinks, are connected to the power supply via heavy-duty PCB connectors. The power transistors are handmatched, each driver - output pair is handled as a composite output element in the "Quad-complementary" configuration.
Worth to mention is the clipping indicator on the front panel. The green LED, which indicates the power-on and normal operation, turns orange when approaching clipping and to red from 1 dB in clipping and up. The indication is very fast and accurate over the whole audio band. I would like to mention, too, that the entire amplifier is hand-soldered, which is at the price and "Made in Canada" quite unusual.Oh, the bottle has been to me, my closes friend, my worse enemy! -

Troy,
You're funny...
Seriously, I'm going to let my dad use them. He has some Monitor 10's right now and likes them, but the folks were down for a visit and after they heard the SDA effect on the 2.3TL's I offered to give them the 2B's. I believe he'll move the 10's to the TV room and replace some small Advents. You know, it's nice to see my (elderly) parents still get exicted about audio equipment after all this time. You should have seen his eyes when I pulled off the grills!

You know I didn't think that they listened to music much anymore, but I quess I was wrong. My father in his younger years built his own turntable and mono tube amp. He had the original AR-1 speaker and as I remember it sounded pretty good. Of course that was more than four hours ago.
Oh yeah, he's a Yammie fan too. (that's for you King Yam)Political Correctness'.........defined

Speakng of cats, has anyone seen my 5 year old's kitten Hunter?
He has left the yard and can not be found, made signs last night and we are offering a reward of $ 5.00 paid by my son. (I will how ever pay $10.00 to have take my other son's kitten Mittens, oh to be cat free again)Dodd - Battery Preamp

F1nut,
Instead of 7B ST... get the 14B SST and it will really drives
you nuts.
Har -
Har,
I looked at a 14ST, it seems to be two 7B ST's in one case. Same money for one 14 as two 7's. The dealer stated that Bryston made the 14 for people who didn't have the space for two 7's. What's your take on it?Political Correctness'.........defined
