Description
This is an EXCELLENT condition SINGLE (NOT PAIR), BRYSTON 7B SST - C SERIES. This is the 17 version in SILVER finish and of course ORIGINAL EUROPEAN 220v. The power amplifier was used for the purposes of the center channel in a very high level home theater system. Please note, THIS IS NOT A PAIR, THIS IS a SINGLE power amplifier offering 1x 600 Watts at 8 OHM. With this power you can simply drive ANY center channel. Very hard to find a single one as they usually selling in pair. As you can see production date is 05/18 . That means 18th week of 2005. So in any case you are still covered under the Brystons 20 year warranty! Retail price for this was 4000 EUROS. Bryston audio products are backed by some of the best warranties in the business. Twenty years on all their analog circuits, meaning every amplifier and preamplifier they make. I find it highly unusually, and very refreshing, to find a twenty-year warranty on audio products. As for their digital gear like the processor and the external DAC they come with a five year warranty and three years for their CD player. To me this makes a pretty strong statement about the company’s belief in the products they sell. Please check their website for complete details on all their warranties. In an effort to produce quality products rather than mass produced quantities, Bryston technicians are not pressured by quotas or schedules.In fact they are offered flexible work hours and have the chance to share in the company’s success. The goal being to carefully produce quality products with a low return rate in an effort to create higher customer satisfaction. According to their website the technicians take between thirty and thirty-five hours to assemble just one amplifier (or preamplifier) so as you can see they are not putting these out in traditional assembly line fashion. The website goes into more details about company philosophies, and being a graduate with a B.A. in Psychology, I must admit that I like many of their ideas with regards to the treatment of employees. After all it is the employees that have a direct impact on the overall product delivered to you the consumer. You can read more details concerning this at their website located under the tab labeled Company where you then will find the sub tab Philosophy.Features And Benefits When the amplifiers arrived they certainly were a sight to behold, two large boxes, very well packed, with one amplifier and one robust looking power cord in each. At first I was a little worried as one corner of one of the boxes had been damaged during shipping. When I opened it up though everything was perfect inside. When I contacted James Tanner the Vice President at Bryston to tell him that the amplifiers were fine he sent me an email saying, Yes we do a drop test on the corner of the box with the product inside when we are developing packaging for any given product. I must admit I was quite impressed. Not only does this company take care in developing, assembling and testing your product but they exert that extra effort to make sure that it arrives safely to your house with packaging sturdy enough to withstand some non-audiophile handling. Starting with the back panel you will find a host of features. You definitely should read the instruction manual first which explains each one, before attempting to setup your amplifiers for the very first time. On the back panel there are both RCA and Balanced inputs as well as a switch to activate either one. Next to this is a switch that allows the user to decide between a 1v or 2v input sensitivity setting. This is basically a gain switch. The 1V setting provides a higher gain of -29dB (1V in + 100w @ 8 Ohms with noise at -110dB). The 2v setting provides a slightly less -23dB (2v in + 100w @ 8 Ohms with noise at -113dB). James Tanner from Bryston recommended that I leave it set to 1v with my particular speakers and I found that worked just fine as I did my review based on that setting.The binding posts on the back have the ability to accept spade lugs, banana plugs or stripped bare wire. I found them to be an excellent set of posts working easily and making proper contact with the cables. If you order the pro model you also get a level control that can attenuate the input signal level from 0dB through -14dB, mine was not the pro model. On my C-Series there was a line voltage status indicator light on the back which should constantly light up green (if it is blinking green there is a problem) when the back power control switch is set to on. Unless you are switching wires or using the amplifier for the first time and are setting it up you should always leave this switch set to on and use the power switch on the front for the amplifier on/off functioning. Looking further we next see an external control voltage power-up switch labeled local and auto. This along with the accompanying outlet is to be set to local for use with the front panel SST Power switch or external if an external source is required to power-up the amplifier. I left it set to local. Lastly the back panel features the obligatory (at least at this price range) IEC connector. Here I decided to first listen with the supplied factory power cord which being 12 gauge was quite robust and worked fairly well. I am however a believer in using after market power cords to coax the most from your components and feel that they can up the performance level enough to justify their existence as long as the price range is keep in perspective with the product on hand. Having numerous power cords available to me I was able to experiment, finally deciding on some Audience e power cords at $674 each to use for the listening tests.These power cords coupled with some Acoustic Revive XLR and RCA interconnects as well as their SPC-PA speaker cables comprised my review cable ensemble for the Bryston amplifiers. On the front panel (mine had the 19 rack mounted silver faceplate with handles versus the 17-inch faceplate without handles), is an LED light to indicate the various stages that monitor the following amplifier conditions. Unlit: Indicates the amplifier has no power Red: Indicates the amplifier is muted (power up) Green: Indicates the amplifier operation is normal Flashing Red: Indicates the amplifier clipping Orange: Indicates channel thermal shutdown During my review period I never was able to drive the amplifier into clipping nor did the LED display ever turn anything but red for off and green for on. As hard as I ran the amplifiers they did not even get hot to the touch. Looking now to the bottom of the faceplate located below the LED light is a power on/off switch labeled SST which is how the amplifiers are turned on when the master circuit breaker power switch on the back is left on. Each amplifier weights about fifty pounds which for me was quite easy to lift and move into place. Bryston amplifiers are all designed to be Mono in that each channel is separate with independent power supplies, sharing only chassis and power cord. Both my wife and I found the silver faceplate design version to be quite attractive in appearance which is always an added bonus. However, now came the crucial part of this evaluation, how did these impressive looking feature ridden amplifiers fit into the scheme of contributing to the improvement of the sound in my review system? To start out with, and for most of the review, I listened using the balanced outputs from amplifiers to preamplifier. My CD, though, did not have a balanced output and there I was forced to use unbalanced RCA cables. XLR Versus RCA Cable Connections Taking a break from my balanced cables it was time to switch over to using all RCA interconnects. Since both XLR and RCA cables can be used with these amplifiers and because not all of us have a balanced preamplifier I felt it imperative to listen with the RCA cables as well. Fortunately for me I had a Monarchy Audio preamplifier which has both XLR and RCA inputs allowing me to check its performance either way. Just a brief note on this, aside from the differences in balanced (which should be slightly quieter) versus unbalanced, the amplifiers did not disappoint me when heard through their RCA outputs. While I did prefer hearing them in balanced mode I would not hesitate to listen either way. The only recommendation I can make though is that I found cables did matter. These amplifiers can take advantage of the qualities a great cable has to offer and I suggest that you find the best you can, then sit back to relax and enjoy what should amount to a night (or day) of great musical enjoyment. The Acoustic Revive interconnects retail for $900 and their XLR cables are $975 a pair so you can see I did not go cheap with the cables. I also tried some Audience Conductor e interconnects which retail for only $391 for a one meter pair and I was quite pleased with them as well. An old favorite of mine is Joni Mitchells Court and Spark [Asylum 1001-2] and especially the title song Court and Spark. Here with the RCA cables I still enjoyed Joni Mitchell playing guitar and singing while her band accompanied her. Without hearing them side by side I would not have been tempted to put the XLR cables back in as they sounded that good even in unbalanced mode. Returning to the balanced XLR cables did however bring with it a smoother quieter feel to the music with just a slightly larger soundstage. If I had a choice I would no doubt go the balanced route, if not I would still purchase the amplifiers today and use the RCA cables until I got a fully balanced setup to accompany it at a later time. Either way these are a tremendous pair of amplifiers.
