Burson Buffers?

I can find out which value Goldpoint later this week, but we used the single ended input on a pair of Aleph 2's.

OK, post the rest when you know it.

The Aleph 2's single ended input impedance is 10k ohms. Pretty low.

...an addendum to my prior post. In order for the Goldpoint attenuator to work properly with the Aleph 2 amps (utilizing their 10k ohm input impedance), the Goldpoint's attenuator value would have to be 10K ohm or lower. The stock configuration for the Goldpoint attenuators is 25k ohms. This is info available from the Goldpoint website.

If the Goldpoint attenuator you heard had a value of was 25k ohms or higher, then it would be a bad match for the Aleph 2, and would explain why the Burson Buffer had a beneficial effect.

To the OP. I know you say you have low bass output from your new 840C. I also have a new 840C. The only upgrade I have is a PS Audio AC3 1M PC. I have never listened to the stock cord, so I don't yet know what difference the PC provides. Anyway, sometimes I think that the unit doesn't do bass so well, then I put in a different CD and voala, good bass. Seems very CD dependant for me. Overall, I'm quite happy and I am running McIntosh power with ML Vantages, which are not known for the stongest bass. I'm wondering if you have enough runnin time (breakin)?... And in the end, I'm also interested in this Burson Buffer. Hope to hear about it soon.

I do remember you comparing the 840C to a Nak cassette deck. Maybe that deck just has less upper end extension and so it sounds like the 840C is underpowered in the bass department. In any event, I hope you figure out your conundrm and a great fix, if that's what is needed.

I have tried their Burson Buffer and PI-160 integrated amp and they are both very good.

The buffer is system dependent. Any source machine with 150ohm or above output impedance should benefit greatly from the buffer. Anything under 150ohm is less preditable.

It pays to contact Burson Audio directly, and they are pretty friendly folks.
