Capacitor

@ Grannyring
I had 4 jentzen superior Z caps changed them and was surprised how the sound improved though they are not burned in as yet just 10 hours
I guess caps do make a difference wondering how the V cap Odam or the miflex copper cap will fare will it be better than the Jantzen caps.

@grannyring
I have same caps with lower value 0.33uf 600vdc in my tube mono blocks also do you think changing them will also bring a good difference

The Odams are much better than the Jantzen Superior Z which I am very familiar with. Different level of sonic performance and nuance to be frank. However, they do cost more.  Where are you located? 

India, that is the reason I am unable to decide, will be buying blind hence your expert opinion I am zeroing in on the Miflex or Odam.

What do you think about the amp caps I asked in my previous post what do you think I should do.

Do you mind sharing what value uF you used? I have a C800 and was thinking of upgrading capacitors too, but the CuTF VCaps I was thinking of using is not made larger than 2.0 uF. 
Thank you
