[quote user="miab"]I'm about to place an order for some 12AX7 tubes. The GA 12ax7 tube you mention doesn't seem to come up in my search. Is there other info regarding this tube?[/quote]I am not sure but it is possible that General Electric never ...

I am not a recording historian, so I can't say as a matter of fact, but I think one big difference between the 1947 (London) Yepes and the (post 1970) DGG Yepes is the guitar.Never mind about the "absolute superiority" of the "balanced" 10-string con...

One of the most pleasant things about the Purepower 2000 (PP2000) that it in contrary to any other power devise I hear it has very limited if any impact to the original sound of a playback. Somehow the PP2000 surgically removes all negative manifesta...

Can we really say that the "lowest fundamental" from an orchestra is 30 Hz? I sort of wish it were true!Something I think we can all agree on is that hi-fi tends to suffer from lower fundamentals and harmonics that are not properly proportioned, and...

Guy, thanks. We are sitting now in backward, resting after heavy landscaping project. The project consisted of Amy picking up some weeds for 5 minutes and then I hit my leg with 35” wood spiting ox. After all she resuscitated me and we firmly concede...

After a provisional cleaning of my crappy Yamaha C2 preamp, I got +/- balanced bass and then made a bit of discovery: Changed the parallel R in the HF circuit of the UK crossover from 50R to 25R (and switched the xcover to the treble boost mode which...

This is left channel. Right channel is mirror image.I am using 6db active crossovers all around.The subs are pair of 18" Aurasound 1808 per side. The current midbass is the white color horn you see. It is Funktion One DS15. The issue with this one i...

Here, you can see the distance to front wall. The wall is about 10cms behind the moss garden.About 35cms to the wooden binary diffusors surface. Another 55cm to the drivers and total distance to front structural wall is about 90cm (2,95feet)Maybe mor...

In his latest YouTube,Romy mentioned using my prepro to time align my drivers.I use the Trinnov Altitude 16 prepro which has a total of 20 channels. 16 of the channels have balanced analog outputs and the othe four Channels use the rca and optical sp...

When you say, your horns are 11feet apart, does this mean from acoustic centre line, or the outside perimeter of the upper bass horn. If it is from the outside perimeter of the upper bass horn you are having a similar setup with mine. When they are a...

Apparently it still happens: good electricity during the day. Wifey went to the fair with a granddaughter, so I took full advantage! If forced to guess why the electricity was good, I'd guess that the nearby school is out, kids are visiting relativ...

Sorry Romy, i can't tell you about life longevity of 6E5P in my amp 'cause i'm not using them there anymore :)For my speakers two-stage SE sounded much nicer, more balanced and clear with more volume. Well at least it was easy to predict, considering...

Hi Romy
6CJ3 (or equivalent) is the one you want. Though I've not used them myself, I have pals who regard them highly, FWIW. It has an average current rating of 350mA, but don't forget that for a given draw on the supply, the average current throug...

It is good, very good. Actually I did not expect that it would be so easy and some resentful at the same time. I was running the new horn, juts single horn, listing it here and there, trying to get a precise high-pass crossover point. The 18.5uF turn...

Sure, I speak of amplification here because that is what we are talking about, but naturally playback is playback, not any of its elements taken alone.I am not sure more detail about the entire system is helpful because no amount of detail is really ...

Last and this weeks I played mostly LP records. I have only one arm and one needle setup after my move to new room – I did not decide that what final configuration I will have for my analog. Today, while I am in Brahms wave I played the entire box of...

Thanks for your advice Romy and Stefano.I have used RTA with condenser mic in my past systems but I admit I am no professional at it. But I am not clueless with it either.. In my previous setup when I was playing with open baffle designed speakers, ...

Cat:First off, the Silbatone Aporia is $30k/pr not 100k. You could do 6 speaker surround with Aporia for well under $100k. Hope you feel better now."So what," I say. $30k is already too much for my pocket. I am on a fellowship this year and cheapskat...

Is there a pill for that too? Seriously, it would be very interesting to hear what solution you come up with because I have converted from listening music solo to a small number of audience (friends). So much that I listen by myself much less oft...

[quote user="Paul S"]George, since you have been using the Equi=Tech units for a while now, what do you like about them, and will you compare the sound you get with and without them? Also, what do you not like about electricity with the Equi=Tech un...

I chose the 170V point as midway between the 250V supply I had for the CCS plate load. The choice was for maximal signal swing in both directions. [quote]in a properly designed amplifier a transformer should clip before the active stages[...

Hi,
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. The rectifier is...

I think there is a definate trend here regarding distortions that cannot be ignored. Guy, you pointed out some excessive 2nd order harmonics with the Melq bias point. Hey, maybe so. I haven't really looked into this tube - but I jus...

I have a box set of Günter Wand conducts his North German Radio SO with 4 Brahms symphonies. It is celebrated recording from beginning of 80s. I like it but it always sound to me like play critical mass of Brahms without any finesse-Brahms. My versio...

I tried the ML2s via their 16 Ohm taps, even though my speakers drop to 4R at about 80 Hz before going back up their average 8 Ohms at 30 Hz. The overall sound off the 16 Ohm taps was more balanced and integrated top top bottom, ...

I see, we just use meaning of “accident” in artistic expressiveness differently. I would certainly do not consider a Cat walking across a piano and playing with her paws the Moonlight Sonata as an “accident”. These types of accidents are just outside...

I do admitt that I have a tendancy to be attracted monochromic works in general, rather than colorful extarvaganza, both in music and visual. The colors, even strong colors, when balanced and co-ordinated under a specific intention, can achieve some...

[quote user="Romy the Cat"] After some consideration I picked today Yamaha B-2 amp. It is V-FET from 1978, it might be interesting. Post Vince’s site or his shop info I might need to have B-2 serviced or modified. I think the 140W of B-2 might be goo...

Reading today about Mani’s Star Ground idea I was thinking that in context of playback we do not truly know the extent of “Star-ness”. If we do not know how each particular component use ground and we can’t not be 100% sure that our primaries and fro...
