Well folks, there is a new cap (not) in town. The description from Humble Hi Fi's updated cap review is nearly exactly what I'm (or I think) I am looking for. They may be difficult to get. Anyone heard them?? Warm, full bodied, intimate character. Yeah! My guess is that they are not $50-$250 each. Tweaker

Hello, I have ability to ship K78-34 caps worldwide, if you are interested in it, you can send me a message.
They are good bypass capacitors for electrolytics in power supplies, but like Uncle Mike suggests, they would not be at the top of the list (or at least my list) as coupling capacitors in a signal carrying circuit (notwithstanding the fact that the signal goes everywhere).
I would choose almost any good film and foil capacitor vs a metallized one. Polystyrene and teflon being two.
Lew et al. Please read HumbleHH's review of the Russian cap. Exactly what I want, in words that is. Many of the other caps are beyond my price range. My main amp is using Nichicon polyester. Shouldn't be to hard to beat. My very limited experience with polystyrene was that they were bright. The one Solen I heard a long time ago , bottom of the rung, cheapest was on the bright side with glare. I'm sure there other models are better. Never heard good high quality polystyrenes but the ones I see are way beyond my price range. The CDE 940c and the Russians are in my price range and are described as what I am looking for by HHF. The Audio Theta PPT gets review as what I want, warm, rich, liquid... by one reviewer and thin and bright by another?? $30 to $250 caps are out of my price range, especially since Uber has destroyed my income.

No harm in trying the K78s. Russian teflons are cheap but very physically large for a given value, but if they fit, you might want to give them a try, in addition to the K78. Other guys rave about the K40, when it comes to Russian oil caps. I've never heard them. They're cheap too. Go to TubesDIY and search on "K40".
I agree as regards Solen metallized polypropylene film caps; they suck, IMO. I probably should not have even mentioned polystyrenes because they are virtually gone from the market in all but very low values suitable for RIAA correction but little else. But, believe me, they could be fantastic back when you could buy them. REL makes a few still, maybe. REL polypropylene film and foil types are pretty good bang for the buck.
Lew, Thanks for sending me over to Tube DIY. Lot's of talk about coupling caps for tube amps over there. Tweaker
Lew et tal, The Rel Audiocap Theta PPT tin foil cap gets a similar review as being warm extra rich and such by a famous reviewer and might be in the running. It is panned as being thin and bright by another muy famous cap reviewer. This first reviewer said they were thin and clinical at first, I think I have that correct, and then completely changed into warm and extra rich after burn in. Quite a transition. I was once told that tin is usually warm?? It's down to CDE 940c,Russian K78-34 and the contradictory Audiocap Theta PPT, I think. The description of the K78-34 by HHF sounds perfect........ Tweaker
Buy your own caps and decide for yourself. Also get a bicycle.
Well Uncle Mike, Looks like I'm going to have to roll a few. Hopefully I won't destroy the circuit boards. I don't think the K78 comes in 600v. I don't get the bicycle thing?? Tweaker

"Still Working the Problem"
They have been around for years...do a search. Metalized poly MKP type cap.
If they have a sonic advantage...likely not or they would have been hyped all to h***. These are relatively cheap. A good example I still know of are the Solen. Work wonders in speaker crossovers
Solen is probably the worst of all the many many caps I've tried in tweeter crossovers and coupling duty, with a brittle, shrill sound that is artificially detailed and bright. They are only slightly better for midrange, or decent value for large shunt caps in a crossover. Sorry to say there is no free lunch when it comes to caps. For coupling, film and foil is the best sounding, and they cost money because they're expensive to manufacture.
To the OP: I'm weary of posters coming here seeking the best sound and whining about their budget. If one can't afford better equipment, learn to accept compromise. A single cap or other component is not going to magically transform your thousand-dollar kit. You might realize modest improvements with a few better parts, but reset your priorities and try to be satisfied. Installing a $5 or $50 or $250 cap is not going to change your life.
Buy the best sounding cheap cap, which is Sonicap Gen I. Or just buy the Ruskies and come back here to tell us it's the cap of your dreams, but not based merely on something you read at HHHiFi.
Peace,

Well madisonears, Is there some kind of general consensus that the Sonicap Gen I is a warm , full bodied intimate sounding cap and that it is the best? Some people find it bright and I believe Jeff also said that some find it bright. The number 1, shall I say NUMERAL UNO! thing I don't want is bright. There are a zillion caps out there these days and something called the internet which I use to seek info. There is a rather small number of caps that get reviewed as what I'm looking for and the Sonicap Gen I is not one of them. But, gee thanks anyhow. Tweaker
So helpful madisonears. I myself have found that a single or a few caps radically change my $2700 "kit". Are you saying that going from a cheap junk cap in a dac power supply to a Nichicon KW is not a "radical" change? Well IMHO it sure was a big change. There was a Ugggg improvement in my "thousand dollar kit with a dollar fifty cap." Great improvement in timbers. The other $2.50 spent on Nichicon ES and KZ caps in the dac upped the sound quality quite a bit more. A bunch of 7-$10 coupling caps to replace polyester caps is not going to be a "radical" improvement? Are you kidding? Not all film and foil caps are expensive. Very helpful. I grow weary of unnecessary criticism, bad information and advice. This site is only for rich people?? Who said I was looking for the best sound? A complete misreading. Your comments bring unnecessary controversy to a perfectly reasonable inquiry. Tweaker
I won't waste any more of my time responding to your swarm of semi-coherent posts.
By the way, "kit" is a mostly British idiomatic term for what we call a stereo, and timbers are pieces of wood.

When you post you get replies. You can't control what they will be. You can add fuel to the fire like you did-not good.

Let the bellows of reason and righteousness make the hot fire of irrationality and uncalled for insult burn out more swiftly. Now Awe-d this is your Q to point out the difference between using bellows and actually adding more fuel. More swiftly, hum , I wonder if that's grammatically correct? Tweaker
We're on the same page here.
