Bringing Bryston 4B back to 1997 new.

I owned the BP20 and also owned Bryston amps in the 1990’s. I also had a Thiel SCS4 monitor with a Bryston 7B-sst and I think a BAT VK-42SE preamp (warm).

The combo of the BP20 + Bryston 1997 + Thiel would be too bright for my ears. I would get a warm-ish Class D amp, such as a D-Sonic

@goldbehen I too wouldn't be paying that for a new cube series but on the used market they can be found and still warranted for the remainder of years. I get a warmer presentation with a tube pre and the 7sq.  Probably though I'd be considered to have a bright system. 

I sold Bryston retail for years, and they are spectacular amps and have excellent build quality. Renewing one is not a bad way to go. However for the same money you could buy a brand new Axiom Audio ADA1000 amp with 250 watts/ch and huge headroom in a very neutral sounding amp. FYI the owner of Axiom now owns Bryston. The Axiom amps are not typical class D, the have massive toroidal transformers and 60,000uf  of capacitance and weigh 44 pounds. Most importantly they sound amazing. The ADA-1000's class-D output stage (designed by Axiom) uses a high-current linear power supply that provides better performance than the switching supplies typical in class-D designs. Very uncolored. I am using a 4 ch. ADA1500 in a tri-amped system with a Legacy Audio Wavelet as the pre-amp, DAC, X-over and DSP and room correction. It all sounds very "analog" with no digital bite or HF irritation. Just my opinion  

I have a bryston 4B that I bought brand new in 1996 for 5400 and I would not trade it for anything it is a fabulous amp and will power and drive the most power hungry speakers out there. The only problem I have ever had was my fault back in 2018 i thought I would be a wise guy and crank the volume  as high as it could go and all I managed to do was blow up a pair of ADS  L8E speakers and clip the left Chanel of rhe amp having to have it repaired since now the red light was on in the front. My crazy actions set me back 500 dollars to bryston to go through and repair the amp. I have had no problems since. 1700 for a 4b is awsome the new 4B is now 8400. Take and match the 4B with a tube preamp and the sound is amazing. I just bought a brand new rogue rp7 preamp along with a pro ject tube box ds3b phono pre amp and the sound is pure bliss. There is not a lot of difference from the 4B you have from 97 and the one they make today other then the base that it can power. 2 years ago when I replaced my speakers with a pair of dynaudio special fortys and upgraded my sub with a rel s510 the sound is awsome and the base is as good or better then what the new 4b can do. For a quarter of the cost that the rel s510 puts out. If I was you I would have bryston refurbish the p you have and you will never need another one. Match it with a rogue tube preamp and you will have a amazing sound. The rp 1 starts at 2000 the rp5 is 3000 the rp7 is 5500.and the rp9 is 7500 all the rogue preamps are tube. The 1 and 5 have a phono section in them the 7 and 9 don't but have xlr inputs and outputs it is a trade off. I am big into vynal and with a linn table my set up is very sweet. Keep and rebuilt the 4B it is one of the best amps out there you won't regret a penny spent good luck Michael. 

Thanks so much for the product prices and timelines. I have spent some time looking for it. I have recently purchased a bp25, and got a 3bst a few years ago. Also have a couple of 2b and a .5b. Seems like a lot when I list it here—some nostalgia here. They do sound great. Debating whether to re cap the bp25–or at least the filter caps. If their upgrade service only replaces caps, I can do that. For some reason, I thought it was more…
