post #2131 of 2935
Clem,

I hear ya. This matching of amp to Strada is a bit of a challenge to figure out . I too am trying to set up a desktop system. This is a Gallo forum but I do wonder how the Jon Blue JB3 would compare with the Strada for a desktop. I've read raves about the JB3 in that role in terms of coherence etc. Anyone here own the Strada and JB3? Highly unlikely but thought I'd ask. The JB3 would be much more easily amplified though efficiency is similar on paper.

Still by far the best pair of speakers I've ever had on a desktop. I am beginning to think that maybe the A'Divas really were meant for the desktop but my impression is still that you will lose clarity with them.

When you guys say the Stradas like power, approximately what kind of ballpark are we talking about? The manual only rates them for 150 watts. I'm currently powering the center channel with an Onkyo 5008 (rated at 145 wpc).

145W at what distortion?

I have 150W per channel into 8 Ohm RMS with low distortion and low output impedance.

But in normal, quietish, running I'm only using maybe 10 of those watts.

That doesn't mean they sound rubbish because I'm not blasting out maximum SPL.

Although Human hearing does hear bass and treble proportionally less at lower loudness.

This post doesn't help your question much!

I think it's the ref 3.5 that needs a low output impedance amp to supply and control that 10 inch unit. High power amps tend to have a lower output impedance that low power amps so they sound better to many people.

It's not so much the voltage an amp can put across the loudspeaker terminals as what the amp can do with that voltage.

I thought the Stradas would be more forgiving in challenging placement. But I can see the Strada's wide tweeter dispersion may be a double-edged sword. They still sound fantastic on certain recordings - teasing me with a taste of their true potential.

I will try to see if there are alternate locations I can devise and will also experiment with acoustic treatment. Not ready to give up yet. I would appreciate any other advice to help the Stradas sound better in my room.

Do you have a subwoofer for your installation? From my experience, the Stradas don't go deep enough to stand on their own, except maybe for some classical music. My experience with Subwoofers with Strada (or 3.5's) shows that Mid Bass can be significantly improved by setting the crossover high and volume low, to overlap the natural mid bass roll off. My McIntosh MEN200 has a choice of Cross Over Types (Butterworth, L/R, 1st, 2nd, 4th Order, etc.), and I find that Butterworth 1st Order set at 125 Hz works well driving the second voice coil of my 3.5's. I even tried keeping the Subwoofer Amp driving the 2nd voicecoil on the 3.5's, with my main amp driving the Strada's. The 125Hz, 1st order setting still produced very good results, which tells me that Strada's must start to roll off fairly early (at least in my room). I have a small Totem Sub that I've tried with the Strada's, and to get good fill in Mid Bass (in my room) I set the crossover to 150 Hz or higher. I think the difference is that most subwoofers are much steeper slope (2nd order or 4th order) for their internal crossover. I read somewhere that Anthony Gallo uses 1st order crossover in the 3.5's. So for my setup with the 3.5's, I am essentially expanding the entire bass spectrum to fill in the missing bass caused by my open, awkward room shape. Hope this helps.

I was just wondering when folks say that the Stradas need 'gobs' of power, whether their talking about 'gobs' relative to tube amps (meaning over 80watts) or 'gobs of power' relative to ss amps meaning over 200 watts.

BTW Kless,
Audyssey XT32 set my crossover for the table top stand mounted Strada center at 120Hz, so yes, even though the Gallo specs claim 45Hz, the Stradas don't seem to produce usable FR anywhere near that low.

When I first got my Stradas, I had a 50 wpc Harman Kardon, and it sounded good. I then bought a 100 wpc Rotel AVR, but didn't like the sound. I tried a number of different amps on loan, and found that the quality of the amp, more than the power, made the difference. I have tried my Spectron amp at 600 wpc with the Stradas and it sounds good. I have also tried a BAT integrated amp at 150 wpc and it was the best amp with Strada's that I've heard. If my console furniture would accomodate, I would buy the BAT. I am using Spectron to drive my 3.5's, and I do notice that more power makes a difference with the 3.5's, but I think Strada's can sound good with any high quality, high current amp over 75 wpc.

Here is the integrated amp I use with my Stradas and it is a giant killer of a system. Not only the biggest soundstage I have ever heard in 40 years of listening to everything on the market, but this has the most detail and definition I have ever heard. I have the amp setting on the 80hz filter running with two small subs. The 80 hz setting makes a big improvement as it takes the bass load off of the amp. Believe it or not, the amp improved by about 30%.

I have the Dodd tube buffer mod, cap mod, and battery supply with the amp also. With the battery supply hooked up, all electronic glare has completely disappeared. A buddy of mine now has one of these amps, and he agrees 100%. He has used many a tube, SS, and SET amps the last 38 years. The company has a 30-day return policy if you don't like it. The break-in period is about 125 hours.

One question for those who use Anthony Gallo SA amplifier to feed the Anthony Gallo reference 3, 3.1 or 3.5 speakers for stereo music listening.

- Do you have a connection established from your pre/integrated amplifier via Pre-out and connected with RCAs on Line In on the AG SA amp?

or

- Do you have a connection via amplifier's speaker outputs and then connected via speaker cables on Hi Level Inputs on the AG SA amp?

Just to comment on that a bit. I had AG SA amp on trail back home for a week and I have it connected via pre-out on my amplifier (Musical Fidelity A308 Dual Mono) and into the Line in on AG SA amp via RCAs. I had it like that for a week and on the first ball so to say the bass was very impressive. But after I turned OFF AG SA amplifier I noticed that AG Reference 3.5 speakers are playing much nicer in the high mid area without the AG SA amp installed. There was more attack, better transients, less spitting noises from singers.
After that 1 week of trial I had to return the AG SA amp and I did not tried the second option to connect it via Hi-Level inputs. This come to my mind later.

I now think that this degradation of sound is connected with the fact that I feed AG Reference 3.5 speakers via my integrated and also used pre-out on that very same integrated amplifier. So there has to be some voltage or current drop and that resulted that the musical picture was degraded in the high and mid frequency area. Maybe also problem lies in the impedance of pre-outs. Dunno. Just to mentioned that I tried almost all the combination of settings on the SA amp. Also the most radical one. Volume on minimum, cut frequency set to minimum, gain on minimum. So in this case almost no signal came to the bass driver and every time I turned the AG SA amp there was a degradation of sound with the mid and high frequencies.



I now think that second option is more correct when AG SA amp is used in stereo mode application. (picture above)

So please if you use Anthony Gallo SA please tell us your practical experiences and what is your preferred choice of connection when listening to the music,

best, d.

post #2140 of 2935
Greetings,

By the 80 hz setting, do you mean that the subs are producing 80 hz and below, while the virtue is supplying the Stradas without any low cut - reproding the full signal as they are able? Or does the Virtue allow 80z low cut for the amp to the Stradas?

Thanks,

There are two small jumpers in the amp allowing you to switch the amp to cut the frequencies below 80hz to the Stradas. You can re-adjust it at anytime. There is a line out for the subs and it is not affected. I have my subs running about 100 hz to give the Stradas more mid-bass umph.

Those propeller posts are the nicest I have seen anywhere. You can upgrade those to copper if you want. Mine does not have the copper.
post #2142 of 2935
Ozark Tom,

Thanks. I'm a bit confused. Many said the Strada loves lots of power. The Virtue is only about 87W into 4 ohms at max. So for an 8 ohm average load of the Strada, I assume it is about 50 watts maybe? Even if it is capable of high current, isn't that a bit low for the Strada?

Somewhat related, would a high current capable 35 watt tube work well then - anyone know? I seem to hear some conflicting reports on what would and won't work well.

Thanks for your comments on the Virtue - I've heard a lot about those amps.

Thanks,
UL

Rememeber, you are not driving the low frequencies if set on the 80hz setting. I have a room 26 ft wide, by 16 foot deep and it gets too loud for me. My wife claims it is splitting her ears. There is a clip lite on the amp that will warn you of the clipping. I have the speakers on the 26 foot wall sitting about 3 foot from the wall and 7 foot apart. The imaging seems to go beyond the 26 foot wall and some recordings are holographic in sound. This gets very eerie at times even sounding like a 5.1 system.

The company is also working on a 130 watt version, but it will not have the Dodd tube buffer in it. For a pic of the amp, scroll down on this website.

OzarkTom,

Thanks. Very helpful. I called the Virtue people a couple of times but could not get someone so I appreciate your comments.

As to the tube buffer, may I ask a few quick questions as it drives your Strada?

1. Is the Tube Buffer bypassable so that you can have both tube and non-tube sound?

2. Is the buffer usable by itself for other amps so that the signal passes just through the buffer?

3. Single tube I assume? How much difference does it make? I'm assuming this would make the unit a hybrid unit?

I am considering the highly rated Bada 222 hybrid tube/solid state amp for the Strada as it runs 190 watts into 4 ohms and capable of high current. It cost half of the virtue but I'm pretty sure that the Virtue is a better amp.

Thanks,
UL
post #2145 of 2935
I definitely agree on the quality vs quantity conundrum, however I found this from 6moons Strada review(please delete if against forum rules).

"It's important to me that my speakers sound good with 'normal' electronics. If they required costly amps to sing, I would have missed the entire rationale for doing what we do."

Special thanks to reviewer Srajan Ebaen and 6moons for the information.
post #2146 of 2935
He went on to say that he preferred his solid state amp rather that his tubes for the Stradas as he felt the point of the Stradas (high accuracy Hi-Fi) is lost when using a fuzzy sounding amp.

1. It has a switch to bypass the buffer.

2. This one is built into the amp, but Dodd also has a separate buffer. That one might be in kit form only, not positive.

3. Single tube and you can change the tube to the sound you prefer. My favorite is the Sylvamia 5751 GB. This improves the sound by anput another 20%.

And when you take the amp off the power grid and run it on batteries, another 15-20% improvement. I would never buy another amp that runs on AC only. It makes that big of an improvement and the Stradas will tell you every improvement you make. The Stradas are truly monitors.

Tube amps with output transformers slows the Stradas down significantly, but hybrids or OTL's are A-ok.
post #2149 of 2935
OzarkTom, THANKS for your help! Sounds like you run it through the buffer exclusively given how well it performs. Not a cheap amp for the power but sounds like a great amp. Thanks!

I am currently running the Stradas as 2.0 in my living/family room. It's maybe another year away for adding the sub as I have a couples of toddlers. So it all about compromises right now. The Strada placement needs to be off the floor (on fireplace mantle) and definitely no sub yet. Also, I know the Rotel RA1062 may not be the best match w/ the Stradas, but am not in a position to up grade the amp right now.
Also, I did try putting up some blankets at the corners. It did not seem to make much of a difference. On some recordings, the human voices still sounds hot and constricted (like a megaphone), the imaging somewhat flat, w/ high frequencies such as cymbals and bells sounds muffled. While other recording sound sound quite fantastic in all aspects, with only a slight hint of being overly warm at the voices.
Anyway, I am thinking that maybe trading in for something with a traditional tweeter like the Paradigm S1 might work better for me.

How many hours have you played the Stradas? The break-in period is about 100-125 hours. Mine sounded flat and constricted unttl they broke in.

The sub will add fullness to the Stradas if you are having that problem.
post #2153 of 2935
Thanks OzarkTom,

That's quite a rave.

At the price your unit is with the upgrades, it is close to a Prima Luna tube amp that is also raved about and supposed to be rock solid. I was at a high end hi-fi shop briefly today and again, realized that I'm a fan of the tube sound. I've heard that the Virtue has a tube like sound if I remember correctly. Since my budget allows only one purchase and I want to make the right now, I'll look more in the Virtue also. Too bad that I don't often find these used. (Nor the Prima Luna tube.)

Thanks again - because of your comments, the Virtue amps is now firmly on my radar, especially if I go with the Strada.

Thanks!

I have read that the Strada require only 40-60 hours break-in.

I'm not sure what to make of break-in improvements. I borrowed some Strada that have thousands of hours on them and they sound better today than they did two weeks ago. Perhaps my brain has adjusted to the sound.

65 watts is plenty for the Stradas. IMO, the Dared would probably sound the best, but I have heard neither. Lower watts with tubes usually translates to better imaging and detail. And since it is a integrated, you don't have to worry about interconnects messing the sound up.

That Dared sure looks tempting and priced very competitive.
post #2159 of 2935
Vjcs20,

Thanks for bringing the Dared to my attention.

In the same price bracket, have you checked out the integrate Bada DC-222 from Pacific Valve who seem to be a large dealer and a straight d shooter. The Bada 222 is impressive in the specs - 95 watts into 8 ohms, and 190 watts into 4 - which tells me it is capable of pretty high current.

It'll be great to see the two compared side by side. Pacific Valve offers free shipping and 30 days return. I'm not affiliated with them at all nor have I purchased from them.

Considering purchasing 1 or 2 Spectron Musician III Mk2's for my 3.1's. I would like to get some commentary/guidance from current owners of these amps in relation to the the AG's 3.1's.

Reason for upgrading is not to increase the spl but garner better quality playback. I currently have a Parasound P/SP Preamp/2205 Mains (220rms) driving the 3.1s and will be replacing both (which have served me well for the last 10 years) I listen predominately to vinyl or feed the current system via a PC based library (through a RME Fireface 400). I should add my listen area (living room) is 16x14 (rugged floor, lot of heavy leather furniture, no sound deadening other than curtains).

Would 1 Musician III be sufficient (I believe so, but curious as to what I would gain from having 2)?
