Moved Reply to the linked thread:[quote user="glaesemann"]In the past you've referred to current loading in the context of cable length. I recently experienced this when I experimented with moving my amps. I needed to increase the IC length from 1 me...

[quote user="Antonio J."] - Regarding C2 the 2000uF/450v cap, he suggests to replace it with 5 x 200uF/200V by Mundorf (he can get them for a good price, probably better those five caps than a single 2000/450). I'm not sure about this replacement, it...

Functionally, these are the same caps I already replaced once/twice (and wrote about) before, namely the big "parafeed" couplers. The unit came with bypassed 4 uF Kimbers, which were fuzzy and slow, so I replaced them with 3.3 uF Mundorf Silver...

Yes, too low efficiency, even worse than Altec 515, (when loaded with small throat, in proper FLH, NOT A7 type "horn" which disqualified it also for my usage... I don't know how "colored" Tannoy would sound with properly designed...

Romy, I am on the verge of an L-pad for my HF ribbons, but in my case I believe it is mostly the MC cartridge response I am wanting to offset, on a case by case basis.Also, this would allow me to adapt HF to recordings, since there are some...

Well maybe the rich Korean fellow just wants to advance the knowledge of audio as he knows it, by droping a bunch of cash at it, which never hurts!They claim that Silabtone will sound like WE...pf I read somehwere that they use Amorphous cores and s...

Fi-analy started listening the FR combo! The setup is somewhat haphazard:* P2S unknown - trying to get 231.5mm recommended by the Germans, took the pains and the cost to design and make a special collar but missing a laser engraved protractor to see ...

[quote user="Romy the Cat"]Brian, and how do you find your MOSFET behaves compare the 12AX7-based cathode follower?[/quote]Romy, I have yet to try. Only got them on recommendation very recently. They're cheap enough to try in a B9A plug-in without al...

Romy's comments in blue :"...Interesting, as all my drivers, the AK151 and K15/40 are high impedance (15R-16R, DCR around 12R). I do not see a lot of difference between AK151 and K15/40..."Apart from the color the baskets were painted (silver Hammeri...

Interesting Romy, particularly the "echo" affect and weird overtones with the aircap. I wonder if the thing is picking up resonances and if the impedance issue is responsible for the overtones... signal being modulated by the varying input capacitanc...

I'm in touch with a reliable technician who is going to build the Melquiades monoblocks for me. He has suggested some changes which I'd like to comment, he's having trouble to find some of the parts. I hope you can help with this:- Regarding C2 the 2...

[quote user="Lbjefferies7"] … I am going to revise my "Mini" speakers for a second system (different location) and I have not decided how serious they should be. [/quote] From one point I would like it to be better, not because it need to be but beca...

Hi to everybody,I have used those caps: teflon V-caps, AN copper, Jensen copper, Siemens at the signal path of a tube power amplifier (300b SE) application. V-caps are technically very good, very clear, less microphonics, but missing s...

Hi Thorsten,
Interesting preamp ideas.
The Silvaweld is also using some rather interesting ideas. For
example, the power supply is all tube (ie. rectrifier and regulator)
with a large choke as well for filtering and using a 300b as the hi...

Have you tried these with skinny-pinned versions of your tubes? I just bought a bunch of 6N6Ps that have pins so freaking skinny that the sockets on the ML2s won't connect with them. These 6N6Ps have the "up arrow" printed ...

[quote user="Gregm"][quote user="be"]I recognise your observations about the Ag vs. Cu sound, but instead of mixing the two materials I think it is better to change the diameter.I experienced 0.5 mm silver wire to be too thin soundvice, have you trie...
|
|
Allo,Well, the divider may certainly be responsible for some softening of transients - in particualr, what values are you using there?Also, the received wisdom is that silver micas are created far from equal; no experience with them myself but I beli...
|
|
John, I see where you go with it. I afraid that I will not be making my drivers – I have no idea how to make them in order them to sound the way I need. I have no problem to design and to make 4" exit compression driver or to undertake a project to r...

In this exalted company its probably not up to much but I've not heard anything else demo-ed that makes me want to change. :)Front end: Vista laptop with XXHighend software (best sounding bargain in Hi Fi). Fireface 400 external soundcardDAC/Pre amp:...

Thanks, el`Ol
What I wonderful devise to position a tweeter on it! It has even perfect size for my Water Drop! It will not help in my case as my tweeter is firmly makes and my MF channel is flimsy but for somebody why would need a perfect tweeter al...

The "mains ground" is not necessarily worth a crap, electrically; it is just whatever ground system happens to be attached to the main service shared neutral/ground bus. In fact, some older systems may yet use the dreaded "floating" ground. I have ...
|
|
A clue!You are not using the ground on the PP3000 unit and have ferrite packages on the incoming mains supply.I am guessing that you have fitted a clamp directly around the power cord.If this is the case, then you are using the ferrite on the ground ...

First, Adrian, Thanks for your feedback on the newer designed 2A3 tubes... very interesting. I've looked at all 3 of these brands before but have not as of yet purchased any (I have a large collection of 45 and 2A3 of various NOS US brands...

Thanks, Scooter.I am glad to hear from someone so quickly.I've been an "audiophile" for only 10 years or so. With the Edgarhorns, I am currently using a Cyrus Brenneman integrated amp (KT100). I also have a Yamamoto custom 2A3 (single plates) w...

[quote user="Romy the Cat"] Nowadays, knowing what I know and understanding why some WE sound in the way they sound I would not expect that you will be able to touch the core of the WE Sound. I know the answers and I know that they are not possib...

In this case, below 50Hz, I think el`Ol is right to suggest that you consider using DSP as a permanent solution. The SMS 1 is in theory the silver bullet... You just need to find out if you can live with it long-term. Best way to find out... Plac...

Actually, I usually try to use liquid alcohol cleaning as the last. It is not that I feel that it does damage but I do not buy all those Jonathon Carr’s stories about the “vinyl molecules” that left out on the needle. Sorry I am too intelligent to he...

Romy, I think you are asking if I have the Edgar subwoofers also. Yes, I do, like giant woodgrain refrigerator in the living room. So I do get some bass response.The Decca cartridges sound different from every other cartridge I have heard...

[quote user="vakman"]Thank you for your reply and honest feedback that there is no silver bullet.In the interest of trying to move forward, is there anyone in Sydney, Australia who has a Macondo based speakers, whom I maybe able to visit and enlighte...

What sound? With Remedies or horns? Funnily enough, a few days ago I played via Dannoys my heaviest cannon - Decca London Reference +FR64S all silver wired, Charcroft Z-foils etc etc. Big symphonic music, not particularly my favorite but... it wa...
