I was wondering if anybody had any experience in using a voltage converter on a 4BSST or BP26.

I am overseas and using a converter to decrease the voltage from the wall at 220 to 110 to match my Bryston components. (moved from Canada to Singapore and brought my gear).

Since I have moved, something does not sound right in my system and I am trying to figure it out......

FYI the converter I purchased is very large and can handle the power requirements no problem, I am just wondering if it could subtract from the sound

Hi,

A couple of thins here - If you hae just moved then I would say it takes a good few days for the system to 'settle' from temp changes in the move.

May I also suggest you use two power convertors and keep the amp / pre seperate.

The transformer will usually help the sound BUT although you say you have a "large" power convertor hiw large is large ?

I use 8A constant power conditioners on my 4B SST's, much higher peak values - They are NOT voltage change units.

8A @ 240v is 16A @ 110v.

If you are staying there for a long time I would suggest your amp is changed by Bryston to 110v, You could keep the pre on the transformer.

Has your room decor changed much? carpet to wooden floors? etc.

Enjoy the music, Andy.

I have used for 5/6 years a Toroidal transformer(5kg, 300W) to down 220V outlet to a 120V SACD player, the outcome sound quality is very bad.   The good is the wall outlet indeed.

I moved back to my native New Zealand after 15 years in the USA and brought my complete rig back.

Before I left I made a mad dash and got three PS Audio P500 and got them reconditioned. I only use one actively, the rest are for backup.

The reason.... simple... you need to take into account not just the voltage conversion but also the 60HZ to 50HZ change

What I found with my BP26 was that while it ran ok being feed 50HZ, the power supply hummed significantly.  When connected to the P500,  all become quiet and sound quality did increase.

Now.... my valve (tube) amps run fine on 115V/50HZ but that might not be the case for the 4BSST?

I run my turntable, my BP26, my BDA-1 and my Oracle CD1000 transport off the P500 (ie 115V/60HZ) . The rest of the gear runs fine at 115V/50HZ

Also not all "voltage converters" are the same. I use a couple of "Big Bertha" Ben Duncan step down transformers from England which are specifically designed for audio.

Potentially the voltage converter you are using might not be of audio quality. What are you using?

Also a Canadian living in Asia for the past 15 years.  I brought over a Bryston 3B I had been using in Canada, and used a transformer that I had made in HK.  Worked for a while, but then one day I had a very large explosion and flames.

Decided at that point that it made more sense to use equipment designed for the voltage and frequency that exist, rather than try to covert.

Thanks a lot for the input,

I am planning on converting them over to 230V, finally found a dealer here who can do it.
