May ask you: how you drive your Reds 10” and the most important do you feel any their deficiency in power handling. I mean after the 109dB Macondo I have tendency to drive the small Reds slightly hard and this LF drive do...

Roman,[quote user="Romy the Cat"]May I ask you, this realization of yours… dose it has any “sound”. [/quote]The one we have build which is a little different (6S45 not C3g, also tried WE 417A, 437A, TX-101 Copper not silver, AN UK Line Output Transfo...

Hi,[quote user="morricab"]Thanks for the info about transformers. It is as I expected, however, that these passive devices are not passive sonically at all. I agree with you that the higher quality of the transformers should lessen the effects ...

I am sorry I do not want to pollute the PP2000 thread with battery options.Right now I am in the process of testing a lot of different comercial amps to see what I will stay with, or which route I will be taking with my system in the near future for ...

user="devo_yan"]I should use at least 2 amplifiers (one for high
frequencies and the GM-100 amp for low frequencies) with a tubes active filter

Yes, you might, though I
am not a huge proponent of activ...

[quote user="Merlin"]No. You are wrong. Harmonically, my SET is quite superb using either 300b or 811 I have unfettered access to the music in it's entirety. Transformer cores just distort the signal. [/quote]
Well, I do not want to argue the ...

[quote user="morricab"]I have a phono stage from the Korean company Silvaweld that uses the 5651 tube in the power supply as a voltage reference. It also is using a Russian 6C19Pi tube along with EF86 pentode as the high voltage regulator. ...

Alas, not much time to deliver the promised treatise...So, tantalisingly, I will suggest this; for the range 1k up, you would have no problem getting a small mumetal OPT made suitable for the 6C33/S2 combination. Actually, I have something simil...

[quote user="Romy the Cat"]Now, how does it sound and what you drive with
it?[/quote]I own or have owned a number of amplifiers with valves before this, Pathos Twin Towers, Audion, Audio Note, Jadis etc. One of my friends who has the same Avantgarde...

(sorry, this is supposed to be posted in the questions and answers colume but I must be so stupid to have it posted here and now I don't know how to move it there.)Hi Romy,How are you! This is Welborne, from far across the ocean, Hong Kong. I have k...

This is something I've been chewing on for quite some time and finally decidedto make it happen: a serious Stax headphone amplifier.I hope I can use this space as a sort of a blog-report on the progress...if not feel free to remove. I've been "forced...

Adrian, Thanks for a most interesting post. I can't fully respond to this as I don't have the new tube brands you have. I posted earlier regarding my personal findings with the EML 45 solid-plate versus NOS however. Ultimately I found that...

[quote user="Bud"]I am about 3 weeks away from supplying 3 Kz ohm to 4,8 & 16 ohm SE outputs for 300b or 2A3 tubes to George Wright, of Wright Sound, and Gary Pimm of Pimm CCS fame (constant current controls to buffer stages from each other ...

Hi Romy,
I currently use a 3 stage transformer coupled amp with 112's, 71a's (as drivers) and your favourite 300B output valves:-) I'm not sure whether I'd go back to a capacitor coupled amp. I just acquired some Tango NC20 IT's to replace the NC...

[quote user="Stitch"]Silbatone made a Demo with those Horns (the big ones)They said, it is one of three existing WE Horns, made 1935/36 (only mod is the addition of the tweeter you can see there). One Horn is made for 3500 Visitors, so we got a 7000 ...

This is my first horn build effort. Been thinking about this since starting to build loudspeakers and finally have a listening space big enough to support a horn system. This is where I am at now, I know there are opportunities for improvement. And I...

Romy,Your Macondo system is something that has been a "role model" for what I'd like my playback system to be in the coming years. And much of what I've learned about horn playback systems I've learned from reading your writing and other posts on thi...

This is my first post here, so bear with me if my set-up isn't as sophisticated as yours.More and more as of late I started to notice that records exhibit surface noise that was less pronounced [or absent] before. I bought this cartridge 5.5 years ag...

I was traveling yesterday and away from the computer until this evening. I'm glad to see my post as the source of controversy and even cause for a public flagellation from Romy. I don't know whether to laugh or to cry. Actually, I d...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

[quote user="drdna"] It is a very old idea to say that higher power is required for good bass response. I do not think you will get any argument from anyone that increased power makes finding solutions to achieve a good bass response easier. [/quote]...

Hi Romy, I recently heard the smallest Cessaro and while I felt that the bass was not adequate for long term satisfaction it was also not a total disaster. From the midbass on up; however, the speaker is simply superb and one of the very best h...

[quote user="RonyWeissman"] It will drive either my Tannoy Gold's full-range, or my 3-way system (Altec 515/Vitavox S2/EV T-350 or JBL 2450). I could also use it just to drive the Altec 515 and use my current 300B to drive the MF/HF of my...

I have heard hundreds and hundreds of audio systems and mine is by far the best. Honestly nothing even comes close. There is a scientific reason for this. MY system starts with a PERFECTLY tuned room...something overlooked by ma...

Thank You
I'll experiment with the PSU a little. The transformes have only 1 Ohm DCR
and total supply impedance for a channel would be ~ 45 Ohm (with two chokes in series) Imput choke looks like can take 1 A current!All Iron is mil quality and p...
