The TAP TVC does happen support a fully balanced topology, for whatever that's worth. I have not discovered anything difinitive about this for myself, however. I can say that I do not consider the unit's situational neutrality as anything...

[quote user="miab"]I have not seen it mentioned but I might of missed it. The PurePower absolutely demands shielded interconnects especially between preamp and amp in my experience. No matter how careful I route the cables, I was getting noise or buz...

Paul, as you write the pendulum effect is unfortnately unavoidable if one wants the levelingfreedome of spikes, so I try to live with that. I looked at Walker...tjaa....$1750 for a record clamp...I also saw how he works on his suspension (look at my ...

Nope, I do not have the itch with ULF sound but I do have a mild itch with ULF concept. The itch is not strong enough to make me to do something but I would like another day to push the boundary of reality and to see what in behind the rabbit hole. L...

That was the 4 way system designed by John Sheerin using GOTO drivers on my request. The tweeter is GOTO 160 with S3000 horn xover at 5kHz. The high mid is GOTO SG370DX with S600 horn xover at 1kHz-5kHz. The low mid is GOTO 505TT with S150 hor...

Jorge,
I know what you mean about horns, Living Presence. I love what my horns do. Palpability. Solidity. In an invisible sort of way.
I have two Ampex 300s downstair...

Preamplifiers: keys to mystery – or…. how a preamp might be not only a load-driving gadget.
Years after years the preamplifiers are being a “terra incognito” of audio people. I admit that preamps are a subject of my persistent curiosity. I was alway...

[quote user="MINGSU"]I think most of reader get my point of the car examples. The main point is to follow the manufacture recommendation on how to use the driver. Of course, if you want to do something different, that is your choice but don't come ...

I made a simple SE amplifier using the 6B4G for a friend. Initially, it was ac heated and sounded fluid & lively with a very agreeable gentle quality particularly with strings and woodwind. But, however I arranged the ac supply & hum bucking methods ...

[quote user="Paul Costa"]Aparently the new powersupply for the motor makes it sound even better, but I have not heard it or the three motor. I would like to hear the three motor but really do not have any interest in owning it. Much debat...

What picked my curiosity and what I found very interesting is to learn if the Running Springs Audio (RSA) flaks own any truly dymick/harmonics not screwing filtration know-how. If it so then it would be VERY interesting to merge with APS does wit...

All-I'm optimizing new speakers, but the deep subject matter is a little new to me. Will this work?Using a pair of Welborne Labs DRD300B SET amps (tapped 8ohms) with a 3-way passive crossover to integrate these drivers. Here is ...

[quote user="coops"]Yes primarily i viseted Thomas to compare tonearms, he has a couple of Schroeders, the new graham Phantom ( mark III ) a vintage Ortofon amongst others. and he has a fine collection of cartridges, as I mentioned he is a very nice ...

[quote user="Paul S"]Audio Note: This room had THE least problematic sound at the show, better tone and more Music. System was not stressed by classical music as they played it, with a “perspective” that +/- “compensated” for the relative “lack of ...

Yes, it is true – it looks like a move toward my Audio Demoronisator

However, I would like to see what and how Fenice does what it does. This new paper MF driver looks interesting. I ...

[quote user="Teflon"]If I understand you, your amplifier uses line level frequency selection at the input to each channel, and the output of each channel is optimized for the frequency range of interest -you worry not about the performance of a chann...

Interesting… I was under suspicion that only Vibraplan allows LF decoupling but here is another California company the offers an alternative solution.

The Vibraplans did work fine and the principle was very simple, I read wha...

[quote user="Paul S"]Joaco, all this will probably be moved back to the "Electricity" thread, which is not really an APS Forum, as it has appeared for a while, now.
Paul[/quote]Yes , I made a mistake ... it will be much better in the Electricity thr...

What I assumed initially is written on the Nordost page.
"The QKOIL QK1 is a load resonating coil (LRC) which generates a passive electronic field that has a beneficial sonic effect on the AC current."

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...

For the sake of helpfullness, I think that we may separate the differences of the ported speaker designs of myself and Petar. What I have described is the standard, pedistrian model of a vented speaker. Petar's is a hybrid aperiodic-...

Howdy all,I have been playing with the Dunnoy concept since Romy discovered it and I agree that it is a very good improvement for Tannoy bass.Dunnoy with reverb injection is a phenomenal experience. I have gold drivers not red but I tried both 10s an...

[quote user="rowuk"]In Macondo/Melquiades thinking, random process means random result - and that is exactly what happened with Dunnoy. A random driver was placed in a random cabinet with a random passive radiator and random cabinet damping. All subs...

[quote user="Paul S"]Adrian, I wonder how you wound up with the never-mentioned FET 10? I prefer it to the EAR 834 I heard. Is this another case where it's full of old caps? I would not be at all surprised if futzing with those caps might yield as ...

Well, I do not like the ESD debut. It was not well though
and not well executed. The sound that they demonstrated is kind of less relevant.
Sound look like was nothing interesting to say the last, sorry it is too obvious

I think the sorry state of the music industry (s/ware, sound) is primarily due to:a) the trend toward audioVISUAL and the ensuing market for productsb) how people listen to musicA) I believe this is self-explanatory; the bulk of the market invests in...

[quote user="Paul S"]It seems from following these threads that no one so far has been content to stay focused on recreating the accidental success of the original Dunnoy/Dannoy. Is this because no one can actually recreate the original, or is it bec...

Yep, Stefano, it looks like we do have similar views about the subjects we touched. Let go back to exploring one of the terra incognito of compression driver – the sound of Goto.
The reason I ask is because no one talk a...

I pretty much know what I need to do – I need to go for shaper filter built in my power amp. The second order I have no is too impactful to midbass, so I need to do for 2th order or perhaps for 4th and try to integrate it. Whatever it will be I thin...

[quote user="rowuk"]Brass instruments function much differently than audio horns. First of all they are built extremely resonant by mismatching length and horn taper. The taper of the bell is there not for horn type efficiency, rather to change the a...
