Bose 901 series VI & Yamaha A-S2000

Audiolabyrinth,

I think many people would be surprised how good things can sound when optimized/dialed in, even Bose.

I am not a fan of many Bose home audio products, but I suspect few have ever heard newer 901s mated with really good gear well and might be surprised with the results possible.

I have heard 901s and other Bose gear sound pretty good in some commercial installations I have heard, so I have to believe it is possible.

Tone Audio reviewed the 901 Series VI recently. The verdict? A lot going for 'em, especially at the $1400/pr retail.

Review here.

Mapman, The second half of the story is that I had two pair of Bose 901 series six, I put both pairs on the main system, The Krell 700cx before I got the amp modded. man, talking about the loudest system I have heard in my life,The 700cx has bi-amp post, I took advantage of that, the bass was kicking my guts thru my back!, like a fricken concert!, people rushed to my house, they said they heard it inside their house with their doors closed, Ha, He,he,Ha, Awsome!, I will not ever forget that either, cheers to you mapman.

I have a Bose 901 Lifestyle system (15 years old and still going strong) in a room with a Yamaha piano, a set of Gretsch drums and a plethora of percussion instruments, from bells to chimes, to guiros, and claves, and so forth. As a musician, and speaking to other musicians, the 901s are really great speakers. Their tonal balance is spot on. They reproduce the voicing of my piano with uncanny accuracy. Bells and chimes and cymbals the same. The overtones from cymbals are amazing. I have two different pairs of finger cymbals for example that have quite distinct tonality. Bose 901s reproduce their individual character amazingly well. I love these speakers and always have. They are not for everybody and they are not audiophile speakers, but they work well for a lot of people and have done so for many, many years. I am sure the Yamaha electronics would work very well with them.

After improving my Yamaha a-s2000 with my QuickSilver GOLD TWEAK I now love my 901's even more so when you match these 901's with GOOD gear they really SING!

What did I do to my Yamaha amp?

Inside my amp I found out by closing those very small gaps between all those connectors inside my amp with QuickSilver GOLD contact enhancer improved the sound of my amp a lot!!!..

I first started by turning on the amp and then unplugging the power cable going to my amp and then waited 24 hours BEFORE starting this tweak !!!........

Next I took off all the connectors wires going to the transformer, amps and preamp and using a toothpick I coated all the connector pins on the circuit boards...I unhooked and coated each connector one at a time... you only want to put a little bit on the tips of the connector pins!..

Some of the connectors had already been soldered to the circuit boards...in my amp it was the darker color connectors...all the white colored connectors are NOT soldered to the circuit boards and do come off.

You do have to be VERY CAREFUL when removing these connectors because you can bind these medal connector pins very very easy!!! I bent two pins on the back preamp circuit board myself so you have to be very careful when removing these connectors!!........

The improvements I'm now hearing from my amp is got me wondering...Did I just found the "Holy Grail" of all tweaks here???!!!...

Before this tweak I was going to upgrade to the Yamaha a-s3000 but now I think I will just keep my a-s2000 until it dies or I die!.....and I will keep my BOSE 901's as my main music and Home Theater speakers too until they die OR I die!...

I had no idea what a AMAZING AMP was just hiding inside my a-s2000 amp!...
