'Sweet sounding' phono stages.

Recommended Posts

G'day all, apologies if I've raised this subject before but this afternoon I was relaxing to a few records (What better thing to do than that on a pleasant Sunday afternoon), and for a change I plugged in one of my DIY Bruce Heran one op amp phono stages instead of my usual DIY ESP P06 phono stages and whilst both are excellent sounding, listening to the simple Heran design one becomes aware of a 'sweetness' to the audio quality. 

 

In the past I've wondered about this many times without finding a plausible reason.  Is it the OPA2134 op amp used (the manufacturer would have you believe that is the reason), the RIAA network used, or something else?  In all honesty I'm starting to think that both factors might be involved and maybe more besides.

 

Purely on the basis of listening it is a very subtle effect but obvious and it doesn't seem to matter what phono cartridge is used, the damned thing just sounds 'sweet'!  Whatever the reason, I really like it.  I guess that it's one of those mysteries of audio!  Fun isn't it?  Regards, Felix.

I'm using a DIY SUT between my OC-9 and Copland integrated phono stage, I am really pleased with the clarity and overall performance.

Considering I paid 70 pounds for the transformers pre loved, I consider it serious bang for buck.
