Antonio, you might refer to Mike Lavigne from Seattle, I have mentioned him somewhere at my site. I do not know if it is the same guy but it is not the point. The too much worthless leisure time in my hands is not the point as well. The point is that...

Hi Romy,
Could you explain a little more about the amp? If I understand you correctly it is a 1 tube stage with solid state (Mosfet or Bipolar??) output. If it is Mosfet then it is likely to be running without negative feedack, is that r...

Hey Cat,Well..my first question would be regarding the application. The big Melq tube is already doing the bass towers...is it not enough current? And wouldn't a proper class A 100w amp with its low low efficiency require something like 1...

I am with you on this one. I am also very suspicious of gigantic, 4-chassis phono stages if only because I just wonder why the need for all those damn noisy parts, along with concommitment connections?So it really pisses me off to admit that th...

I think I have had enough time with this phono stage now to make a few remarks about it. In keeping with the spirit of this website I am not recommending this component, just reporting on it.
I got my unit off AudioGon after keeping my eyes pe...

Rather involved discussion about Helmholtz-type speakers. Here's another proponent, Hans Kortenbach:https://www.youtube.com/watch?v=LHBlikzKoRgI have only "heard" the Musical Affairs speakers on YouTube, but I have to say, they are able to do some s...

Let start from the largest drivers and go down. There are larger then 18” drivers (23” and 30”) but looking at this magnet structures I do not find them serious. I addition to make the 23” cone stiff enough requires a lot of diaphragm’s mass or to us...

Public radio WGBH (89.7) reportedly bid $14m for WCRB (99.5), Boston's fledging privately held 100% classical radio station. Reportedly the idea is to make 89.7 a pure news format, whereas it previously was a hybrid including classical music. WCRB wi...

OK, I have one foot back in the water again, a hand-me-down monoblock from a "well-respected movie sound producer", to whom I am connected through dear friends. Like most "sound professionals", he is fairly dismissive of the way "we" hi-fi nerds go ...

Hello Roman,Hola from Hong Kong! How are you? Haven't been here for long time. I have a question at the back of my mine for long time, and it may have been covered elsewhete in your blog before. I am asking it here but do point me to the thread if it...

Murataltuev, I am not qualified to advise about the fine points of horns, per se, but I am guessing the big "slab" in the middle of each horns tower will create more problems than it solves, at least with respect to sound. Honestly, unless you are OK...

Shannon, from your questions I "understand" that you want to drive lifeless speakers with a hybrid amp that features a 6E5P first stage. Is that what you want to do? What do and don't you like about your present set-up? What do you hope to change an...

Do I remember that a big part of Romy's choice for a pre-amp was based on the specific needs of his DSET Milq, with it's inter-stage X/Os? And do I remember the Placette Active Pre-amp has consistent, fu...

[quote user="el`Ol"]Here is the link:http://www.rank-concept.deI have no experience with the Lamm ML-series, I just listened to an M-series hybrid amp combined with the Watt/Puppy 8. This performance was a single fake (though a pleasant one). I can´t...

Have put all my DHT's on the curve tracer to see if pairs can be matched for preamp duties. My stash of 10y/VT25/801a/VT62 are generally all very new or NOS specs with mu and plate resistance varying a little, but generally close to nominal specific...

I thought the B1 was Yamaha's V-FET and the B2 was a later "hybrid", but I suppose both are Vintage Sufferer's wet dreams. I have never heard either amp, anyway.
Yamaha B1 and B2 conceptually the same amp. B1 is made only with one polarity V-...

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...

Hi Jarek,Apologies for missing your post.To answer your questions:(1) Yes and no. I've bundled the preamp into its new chassis (that I made from scratch) and it does not sound as good as before. There is a grounding problem with the new installatio...

I heard back from Lamms about the relay pulses. They suggested I bias the amps again and then Lamms went silent when that didn't work. But the problem disappeared when I got around to replacing the 12AX7s that came with the amps.&nbs...

So, I have been looking into suitable valves to base a preamplifer around that are suitable for driving the DSET's. The pre must have a broad bandwidth, low output impedance, some current drive, and not be prone too easily to microphony. Oh, and pr...

Hm, I did not realize that that it was a preamp. I thought that
it was a hybrid power amp. In preamp the Y10 probably might sit at lower
voltage. I have no idea how can they talk about preamp and do not talk about
what output impedance it has....

Being a trumpeter, I certainly have an opinion about this - on many levels.I believe one of the major benefits of a trumpet (horn) is the ability to completely melt into the orchestral fabric or with ease move outside when MY voice in my opinion has ...
