Get the bryston 4b3. You already like the bryston sound and it will give you greater extension in all areas of your system.
What Power Amplifier Should I Buy?
I am looking to increase my system power. I currently am using a Bryston 2.5B cubed, which is specified at 135 Watts/CH. I am using Revel f208 speakers crossed over at 120 Hz to a 15" HSU sub. The f208 speakers have 88.5 dB sensitivity (Amir measured 88-89dB SPL at 1W into 8 ohms). I sit about 7.5 feet away from the speakers and listen up to 92 dB SPL, but mostly stay between 80-90 dB SPL at my listenin g location.
I have not had power issues. I've never seen a clipping light. I just want more oomph. I've never had a power amp with more power than the 2.5B cubed.
My budget is about $5K. I have been looking at some used 4b cubed amps.
My preamp is a vintage ML No. 38s. Digital from Bryston BDP-3/BDA-3 combo. Analog using Koetsu RS and Shelter 901 cartridges into an SUT (20x) followed by a very vintage Paragon System E used as a phono preamp (I have fully repaired this preamp, particularly the power supply).
I like the sound of the 2.5B cubed. I had a Cary 120 tube amp for some time, but grew tired of the heat and the continuous maintenance, including the insane prices for tubes. I did not experince that great "tube sound" that others rave about. I sold the Cary and went back to the 2.5B cubed.
Will the 4B cubed disappoint?
What other amps should I consifder, new or used?
Thanks for your help!

I had the s@me concern as you, and I recommend a look at the Odyssey power amps. I replaced a 100 wpc tube amp with two mono Odyssey Stratos Extremes with several upgrades, almost making them equivalent to Kismet amps. 200 wpc, and the improvement was marked driving my Fyne Audio F-702s. |
Perhaps a pair of Bryston 7B SST monoblocs? If you like the Bryston sound (I do too) you can get a set of 7B SST (Super Steve Tanner) used with years of warranty left for 4-5K. I drive my woofers with these and the upgrade in sound quality and oomph was stunning. (Formerly I drove my 6 way towers with an Audio Research VT130 which is now the mid/tweeter amp.I find tubes to have flabby bass at loud levels) |
