Generally it is very uncharacteristic subject in audio: the destiny of audio reproduction. Destiny might be only with something that has its own lifespan. Audio reproduction is in a way an imitation and therefore should hot have own destiny because i...

Allo Romy, Air core caps? Good man! Are they for trimming or the primary RIAA? The way I see RIAA equalisation, there must be some optimum tradeoff between high R and low C (low value caps are always nice) and low R high C. Why do we want low R? A f...

Hi Scooter![quote user="scooter"]
I have tried the SR-009, SR-007, SR-507, and SR-407 many times over a total of some 5 hours with a variety of sources but always with some Stax branded amplifier. Every time I thought / suspected that the big Stax...

Allo I tell you what it is that's putting everybody off, it's that bloody input stage biasing arrangement... The other thing is that people who know enough to build it have probably read a bunch of stuff here and there, and therefore been anointed in...

Given that you are using a solid-state preamp with presumably lots of driving power, you might consider a 1:4 stepup and use of either an EML 20B tube or the AVVT AV8 tube. That might get you enough gain. I think Rankin used the 20B in his Mercury am...

Romy,do not spit in my eyes as I do have solid state PassLabs 350.5 but even with this 50W Class A amp (push pull) it is exactly the same problem if it is switched off completely even for a short while. I can take ~ 2 - 3 days to be back to norma...

I am new to this interesting site, and am hopeful of getting some assistance with a project. I have purchased a set of TAD 1201 mid-bass drivers to begin a 4-way active system for critical home listening. (in a dedicated room, 21' x 25' w...

Hello friends,For long I wanted to address the issues of too few power outlets and improvement of AC quality. I currently use two $10 power strips. I do not have $2000 for APS purepower, so maybe some one can help me start off with the basics. I have...

can this be anything else but futile?1) If analogue the first thing be the cart, if digital the payer?2) If analogue the phono cable being the MOST important one in the whole system, and could yield some noticeable improvement.3) Has the system got a...

I assembled SUN 2A3 amp for my friend and found it to be quality kit and very easy assemble. Kit was old .I think late 90's so maybe quality deteriorated since then. I have variety of 300b Czech tubes and (Eml 300b , KR 300BLX 842VHD ) bought t...

Yes, well - I wasn't really saying much; just a vague hypothesis. There is some tendency for lower Rp tubes, (and somewhat related) tubes with a certain harmonic structure, to sound more romantic, and hence impart that quality to music regardless of ...

Romy,You are an idiot as proven by your inability to spell. Your degree of electronic brainwashing is exceeded only by the offensiveness of your derisive descriptions of those who reject your fantasy paradigm. How is it possible that a tube amplifi...

Hello,
I've never had an SET amplifier in my system. Having high efficiency horns (106 db on average down to 100Hz ) I have tried a number of solid state and tube amplifiers, and I am aware of their sound in my system. ...

Hi Roman... you WELL know I'm not an in-deep speculator, lacking the "technique" needed or simply the skill;-) to do so... I honestly consider hinting and provoking any interest a much welcome reaction... the "gainclone" project - as I wrote - will b...

Well, I use mostly the “Onzow Zerodust” or the “Solid-State Stylus Cleaner” and alike which are gelatinous gluey jelly into which I dip the needle. The keep is do not immerse it too deep into jell or it would builds up behind the needle and then you ...

Yes. For prototyping.I found out that Luxman built an 8-tube unit exactly like it.I borrowed a picture from the net: www.webbtjanst.se/temp/2003.jpeHowever I think it might be interesting to build one, with decent pots, 6dB filters and 6 buffers afte...

Hi Roman, yes it is true that it is a bit foolish to refer to Krell and Mark Levinson, but I had to refer to some familiar brands that are in high regard among many of us. Many audiophiles from the Far-East (Hong Kong, Taiwan, mainland China, Si...

Hi,I thought on tetrodo (KT-88, KT-120, KT150) and write pentodo, sorry. Wherever the tetrodo sound were nothing special I personally find them a lot of better than solid state, that why I was asking, and these days one can have 300W with to KT150 P...

Well,I did speak with Damian in Technical Support at APS, and he informs me that this effect is something that they have reproduced in their lab, but only with extremely efficient loudspeakers and certain power supply designs in the amplifier. With ...

Paul McGowan is a regular poster on youtube. I have to take his presentations with a grain of salt as they always conform to sales pitch for PS Audio products, but they are interesting. Recently, he asserts that tubes in preamp stage will provide h...

I am actually doing the bass and ULF with different modules and amps. My bass modules are the dual tad boxes driven with their dedicated monoblock solid state amplification. The tapped horn is working for ULF only as it is crossed at 30hz with 18db. ...

[quote user="Ronnie"]I put together a hot tube amp channel, and gone is the sound of shattered glass.All three of my receivers were distorting equally horribly.Beware of never-been-serviced vintage solid state, I guess!Anyone know if it is common for...

Hi guys and Romy,I was inspired by Romy's recent videos on Dunlavy speakers, sound, and it got me thinking, about simple correctness of sound, when I seldom experience it. It happens at surprising moments sometimes, when you least expect it. This rea...

I do not know how the battery operation – I never was too warn with this idea but to have a small Solid State single-ended amp with put transformer sounds to me very nice. I wonder if anyone looks in this direction. I do not know what MIPA amp from a...

Thanks Romy. The monopole issues I referred to are in the areas of coloration and presentation throughout the spectrum, that can be solved/masked effectively with dipoles. I am very aware of the dipoles' shortcomings in the bass area but they do not ...

IF you can "hear" SS amps, Romy, then your system must not be well set up, and be sensitive to the frequency shifts caused by tube amps. SS amps have NO sound that humans can hear. I use EQ'd high eff multi driver horn system, and I can tel...
