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

@grannyring,
Although your comments are addressed to @jasbirnandra I’m sure others viewing this are obtaining valuable insight. Not that yours (Or anyone’s) opinion is absolute but certainly it provides some general distinctions between the various capacitors sonic signatures.

Before deciding to commit to an expenditure on capacitors it is very helpful to have some degree of appreciation for what their sonic character/signature may be. For most it is not feasible to buy every single capacitor of interest and test them in one’s audio system. Someone such as you who has heard a large sample size of capacitors can offer meaningful guidance.

@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.

@pauly, 
Well earlier in this thread you gave warning. Prophetic you certainly were.

@pauly,
"We really need a mute button."

Well folks have stopped responding to those posts directly , so he’s essentially talking to himself. When you are so ridiculously arrogant to tell people what they hear, select and prefer is wrong and misguided, that is pure foolishness and beyond the pale.

@pauly,
Congratulations! Glad to hear the ODAMS capacitors worked out so well for you. No longer feel the need for your subwoofer? Now that's impressive!😊

@jbhiller ,
Lou Rawls and Les McCann? Good taste my friend 😊.
I believe that the vast majority understand and can relate to your upgrading capacitor experiences . I’ll leave it at that.

@jbhiller,
The lack of even a modicum of self awareness to recognize the level of patronizing behavior on display  is stunning.

"Some people are simply not worth interacting with"

@pauly, right again.  It is a pointless endeavor I have to admit.
Charles 
So if a listener actually compared the Duelund CAST, VH ODAM  and Wima capacitors and having heard them (In his components/audio system) found the Wima the least impressive he is wrong and misguided?

Wima is the only correct choice ? The other two capacitors are merely flawed, inferior, colored and distorted? It is totally irrelevant if the listener prefers the sound quality of the CAST or ODAM ? This preference is simply borne out of ignorance and lack of understanding? Yet this attitude is not condescending? Okay I get it. Someone needs access to a dictionary.

@pauly you had it right. So much for my extending "benefit of the doubt".
Charles
I believe @rauliruegas is sincere and has good intentions but he consistently has a ’know it all’ condescending manner toward other posters on this forum. I believe that he is convinced he has more exposure/experience/involvement/understanding with live music up close than ’any'  others here, so he must be the authority or arbiter of what’s correct.

He cited a few of my comments above in reference to Duelund CAST Copper foil capacitors. Well I stand by every word that I wrote. I judge strictly on what I’ve actually heard, no apologies. If he finds the Wima the best example of an audio capacitor, good for him. Others can if they are interested or curious listen to them and judge accordingly. I’m confident in my assessment of the CAST and as always YMMV.

@jasbirmandra,
I have replaced the Solens capacitors in my Coincident Frankenstein 300b mono blocks (One cap per channel) with the Jupiter copper foil capacitors. They  are very high quality and very good sounding.

I believe that the Duelund CAST Copper foil is even better sounding. As you well know this is all pure subjectivity and reflective of individual taste.

"I am blown away by the improvement given the mediocre 3.0uF signal caps are still in place. It sounds like angels are in my room singing to me. Strings just hang in the air and the low level detail is almost overwhelming."
Congratulations @pauly,  happy for you. 
I don't know  why some would question the benefit of changing to superior quality capacitors versus price point influenced stock choices. 
Charles 
I can certainly see Duelund CAST capacitors approaching the prohibitive price range if a speaker crossover has numerous capacitors and  in the higher uf ranges. I was fortunate/lucky.  I had Only a single 5.5uf capacitor between the midrange drivers and tweeter.

Replacing the Solens with the Duelund CAST was immediately heard as an improvement ( Even though quite honestly the sound was very good with the stock Solens). Sound quality continued to improve as the CAST accumulated hours of break-in. But fresh out of the shipping box  it was an obvious sonic step upwards.

 " the Duelund CAST Cu(Sn).  This is the best sounding capacitor ever produced in my opinion"

I'm not in a position to declare it the best sounding as I've not heard all upper tier competitors.  On the forums I see from time to time comments critical of the high cost of the Duelund CAST Copper foil capacitors. Some audio products are overpriced and overrated relative to  similar quality alternatives. 

In my humble opinion Duelund CAST is not overpriced.  In this instance you get what you pay for.  In fact I consider them a value choice because I believe that their performance level is that noteworthy.  As I've said before in regard to them, they are worth every single penny charged for them. A superb sounding product. If you can comfortably afford them, buy them. There will be no looking back. 
Charles 

No doubt that the cost can escalate with having to acquire 4 capacitors depending on the particular one chosen (Interior space is a consideration as some capacitors are large). I can absolutely vouch for Duelund CAST Copper  foil capacitors. 

 Put them in my Speaker's crossover (Only required 1 per speaker) and as output coupling capacitors in my DAC. This was grannyring's suggestion to me years ago.   Simply superb sound quality outcome in both instances. Worth every single penny to do so.

Canary Audio amplifiers do tend to have high input impedance.
@jasbirnandra you're in good hands with guidance from @grannyring😊.
