Capacitor


Dear friends I am interested to upgrade my caps in the tube preamp from Audio theta tin foil 3uf200VDC to Miflex1uf 240VDC copper foil what are your thoughts will reducing the value to 1uf affect the bass and frequency response or should I go with a higher value than 3uf

Dear @jasbirnandra  :

Wonderland ( thank's Pauly. ) caps are designed and manufactured on purpose for : tone control. I'm not who is saying that but what exist in internet sites and that's why you are " happy " with and now willing to buy other 18 wonderland caps and of course your " technical leader " is whom support you as pauly too.

Here a second fact coming from different source white papers where not only you but all the wonderland  caps users can confirm the other link. Please read all the pages an carefully the pages 4-5-6 and you will know why the wonderland caps makes everything but function as a capacitor to fulfil the electronics needs ! ! ! :

This is what your electronics needs. What you buy is different and your privilege, the amp can't " choose " other that what you want:

Look at the charts and ask Jupiter or Odam manufacturer that gives you that information.

I consider the odam very reasonable cost cap, if sq as good as grannyring says, incredible value. In the whole scheme of things $300-$400 not bad. Loudspeaker crossovers with their much large impedance values, and prices, makes electronic cap mods look relatively cheap. My next cap mod will be the odams for sure, likely next few weeks. Their relatively small size is also in their favor, I've faced big hassles in regard to size fitting past film cap mods.
@sns, 
Agree! That big Canary amplifier is expensive, highly regarded  and I'm sure sounds divine.  If 400.00 dollars worth of quality capacitors pushes it further then that's quite the bargain/value proposition. Improving what is already very good.

What do you think about the HT jupiter paper wax for the amps or maybe the Rike S2 cap or Audyn true copper will they be better than the Audio Theta

Again, the HT’s will cost “about” the same as Odam? Why not go for the better Odam?! The HT’s are warm and full bodied sounding. Very musical. They are not on the level of the Odams however in most ways really. Not heard the Rike.

Yes, the HTs are better than the Theta. They will not give you the realism, inner detail, dynamics and bass articulation of the Odam. Jupiter has stopped making the HT as they are very time consuming to make. Limited inventory left on them.

The True Coppers are also better than the Theta. Just because they are film/paper and foil like the HT does not mean they will sound as good as the Odam. They won’t. You may have an aversion to the Odam’s based on something other than price? Seems that way anyway.

Don’t go by Humble Audio cap reviews solely as the caps were ONLY tested in a speaker crossover, not electronics. That is a very important distinction. Also, on a tweeter mostly! Caps can and do perform differently in high voltage electronic positions.

The Odams are not at all over detailed or bright or forward. No, they are richly detailed with natural warmth and fulsome bass foundation. They are the best of the ones you have mentioned. Frankly, I like them as much as the much more costly Duelund CAST in electronics. Yes, that good.
