Alrhough the phasure stuff does sound very good, I do not consider it to be “the bleeding edge”. I consider a preamp allergy to be very typical of those “making a point” for instance! Declaring that only 0.6V sounds good on the DAC demonstrates yet m...

There seems to be a standard 2.7V option for you:http://www.phasure.com/index.php?PHPSESSID=rdq01o6tv8ed20nii15hjqnjb0&topic=1560.0"Output level for Single Ended Mode (RCA) is 1.5VRMS (-3dBFS relative to normal Full Scale). Output level for Diffe...

How many sources do you currently have? If you are building a phono corrector, make it for 4 volts output. If you have a PC for digital playback, there are good DACs with more than 2V output. That would leave a tuner to pimp - certainly less risky th...

I guess the first step is to determine the audibility of K2 at the frequencies being reproduced. Then comes the trick pony if the audibility hurts or benefits playback. Is K2 even a problem?What will inevitably come up is that you will have to engine...

My Dad died a couple of years ago and of course, he had tools and a bunch of other things. His wife, a lutheran pastor asked the question - when will this no longer be „his“ stuff“. Sure, she legally owns everything but when is she free to sell or gi...

For all practical purposes, ESD has“proper“ horns and apparently decent drivers. Thus, we have a chance with this collection of bits to have some decent sonic results. Now we just need a process, perhaps the most difficult part....

[quote user="Wojtek"]Out of a tiny, tiny minority of people who are into better than standard home sound reproduction only 1% would benefit from what is written on this site. It would be actually suicidal to any manufacturer to follow Romy's axioms ,...

If we buy a Rolls Royce, a Ferrari, a Bentley, the manufacturer does not give us a driving course, but they are there when we have problems on the road. They even know what the problems are in advance. They have a towing service. Should the 6 figures...

It is unreasonable to expect "immediate gratification", but I will be watching to see if there will be more interest in sound than in technology coming in the near future. To be honest, the advantages of carbon fiber or high BL are FAR BELOW the corr...

[quote user="Djjjj"]Thanks a lot, rowuk.I do read the Macondo axioms again when I got your suggestion. We never think our system is a perfect one, we will and must do our best to improve our system and correct flaws.Hope to keep in touch and get more...
|
|
Djjjj,instead of reading the Macondo axioms, you ignore me and ask if I have listened to the ESD system. What difference does it make if you do not know what I am talking about? Yes, there are serious flaws in the ESD system. If this is the best that...

|
Djjjj,you completely misunderstand what this website is. It is Romys personal diary. It is not a DIY blog, it is not a venue for commercial exposure. I recommend that you first read the posts on the Macondo axioms, then rethink why the ESD would have...

Slam originating in SS or PP amplifiers? SET being boring? Josh disqualifies himself seemingly at every turn. Instead of embracing the situation and learning something, he just digs an ever deeper hole.In any case, I question if he has any following....

Acousticians drool all over themselves with subjects like this - something not supported anywhere in the entire history of pitch. History shows a constant climbing of pitch - much of it based on the development of wind instruments. Trumpets, flutes, ...

A “casual” look at full range usually results in 3 or 4 way playback for standard dynamic drivers or horns. There are a handful of “full range” commercial efforts from Edgar, Wilson, JBL, etc that are doing similar things with the range of each chann...

Today, it would mean Johann Hermann Schein - Was betrübst Du Dich, meine Seele - Weser Renaissance Ensemble Manfred Cordes.There are other days where it is more like this.https://goo.gl/images/wUFxfBThen again, there is a recording by the vocal group...

Our hearing is very elastic for everything except phase. We can learn to compensate for errors in frequency response easily. My personal experience with sense of space is also very much an acqired response. When I listen to my playback after a coupl...

We know that speaker surrounds are subject to memory effects. Is not playing the speaker (keeping the voice coils warm and surrounds elastic) not the big part of having to warm up the system?With power supplies containing modern diodes, caps and resi...

There are so many things that pop into mind when reading this thread - the "expectations" of a visitor, Roman knowing before the guest is even there what the outcome will be and then for both sides "proof".Yes, anyone who even has heard of Macondo an...

SoundCard22,at one point in time you will realize that the music that you mentioned does not have the technical qualities to discern performance of any high quality playback. Very primitive engineering techniques hide color, space and dynamics. This ...

[quote user="Paul S"]Sure, forget the sales pitch, but some of similar might be good for fairly wide range MF. However, based on the sound sample, it's hard to say much about this one, apart from what looks like an extra load of multiple whizzers at/...

Considering that Srajan is the ultimate audio reviewer, it should be clear to all that there is no opinion worth considering in that article.Where is the cone area to recreate anything except a fart? How is any type of low distortion HF possible with...

My audio IS a musical event. If we remove the musical appreciation, what are we playing back? Why is playback even important? To feed our ego?The relation of the recorded event to the playback is different, but the relation to my senses share many of...

Amir, I question your statement. There are so many senses (visual, aural, touch, smell). These senses can be fooled very easily.We do not need audio playback for anything except our own personal pleasure. I insist that there is no way to measure pers...

Why should we believe this? Is this not the very trash that the modern audiophile company uses to get people with more money than sense to "upgrade". How good would the system have to be to show the difference?...

My point was that a volume control on the input of a DSP is the worst of all solutions. Either lose the DSP (best solution) or create a multichannel attenuator for the output. It will need low impedance to drive long cables - that means an active buf...

[quote user="gurevise"]Ideally, you'd want to drive 35 feet of balanced interconnect with the low impedance source ( say below 150 ohms or so). How low depends upon interconnect capacitance. You can try Jensen output transformer to convert SE to Bala...

Maybe you should get spectral data what your power supply secondaries look like in an case, my suspicion is that we have the exact same issues as with high order crossover networks when our power supplies have "high order" filtration. Maybe we ne...
