Hi folks,
I have a 'budget' tube pre-amp in my stereo chain that serves as both my headphone amp and tube buffer between dac and stereo amp. Sharing the link below for the unit for schematics ( as i dont understand circuit designs).
Link: https://www.aliexpress.com/item/4001002338010.html
The seller's website mentions that the unit gives an option of changing out the OPAMP. It currently has the NE5532 and can be changed/replaced with a Muses 01 or Muses 02 op amp. Ive heard demos of topping d30 with Muses01-03 and liked the Muses02 and muses03. Muses 03 is a single op amp chip and will have to put 2 of these with an adaptor to make it work, so tending towards Muses02. Seems like the tubes (GE JAN5654) are good enough to avoid tube rolling.
Wanted to understand from others experience:
1. Does the OP AMP chip impact the headphone output 'only' or does it effect the line out signal as well? Related to same question, If i changed the op amp to Muses02, will it also effect the sound signature of signal being sent to the power amp via the RCA line out as well?
2. Does anyone else have experience of MUSES 02 op amp (rolling) and the changes/benefits they heard? My goal is to improve the sound stage and in-room presence from the system (other factors like speaker set up, treatment, etc. being taken care of). Would the amp op rolling to muses 02 make a difference?
3. I use Hifiman Sundara's with the headphone out. Would you suggest any other op amp that would be better suited for these planar's?
4. While both mouser and digi-key offer the op amps for sale however both purchases will be subject to customs duty. The tube preamp cost me around 5.5K while the MUSES02 chip itself will cost 6K. incl. shipping and customs. Is there any local/india seller for buying authentic op amps?
Any insights will be mighty valuable
Tx
