What are some great 300B SET amps $5-7K?

[SVS]

That would seem like a reason to build inexpensive high-powered SET amps around it, as it’s been done for 845 (make of it what you will). It would certainly NOT be a reason for top echelon designers to choose it for their flagship amplifiers (e.g. the Lamm ML3 costs 140k).

I think the reason is different. GM70, 845 and 211 tubes are close, but Lamm has known and used GM70 for a long time. In addition, GM70 is more powerful.

I emphasize again that in my opinion the amplifier is so expensive because it did what almost no one does: the lower operating frequency of 8.5 Hz. This makes the sound more natural.
I say this because our internal standard is 7-8 Hz and a comparison with amplifiers with a lower frequency of 20 Hz is very strongly heard not in favor of 20 Hz.

In our 6C4C monoblocks, we got 4.5 Hz (upper frequency 60 kHz).

I wrote about objective parameters, and we have a dispute about personal perception and I do not see the meaning in it, because we are all different.

We can make an amplifier with a much better sound for 10% of this cost. For example, as in the photo.

Hi SVS!

Have you ever considered a parallel SET monaural amplifier with four 845 tubes to produce 100 to 120 watts?

Thank you.

In the photo, SE monoblocks on two 811A tubes with a power of 45 W each. 100W on the 845 isn't a big deal either. The problem will be that this amplifier will weigh about 100 kg, and the US post service accepts parcels weighing up to 20 kg from Ukraine.

How can an 811a make 45 watts of audio power when it’s max plate dissipation is 45 watts…not much more than a 300b. I think WAVAC used this tube and got around 15 watts output.

2 GM70s will give you up to 80 watts of Class A1 power.

2 x 813 can get 65watts

 

[SVS]

2 x 813 can get 65watts

1xGU-80 can get more than 100W.

Do you want to take a lesson?

Thank you for your reply.

Is none of FedEx or DHL or United Parcel Service operating out of Ukraine currently?

I just received a package from Ukraine last week.

I wasn’t aware this discussion was all part of a sales pitch. According to what you’ve offered so far, it follows you haven’t heard much, let alone the Lamm ML3, and now you’re claiming your amp sounds “much better” as if you did know it? I’d be curious to hear your amp in direct comparison to e.g. the Amplifon SET42SE, another GM70 you apparently haven’t heard, and which itself is priced at less than 10% of the cost of the aforementioned Lamm, as your evasive argumentation up to this point does little to back up your claims.

We are at war now, as you know, so the air service is not working. And these carriers use only air transport. The postal service transports by ground transport to Warsaw, then by plane to the destination.

We will gladly cooperate with you after the war.
Thank you.

Suddenly, something similar to an advertisement came out, it's true. But she was directed by your team, so don't blame me.
In principle, we do not have amplifiers for GM70, but for comparison I can provide monoblocks for 6?33?. If you agree, we can discuss the details.

The weight of each is 18.5 kg and there will be no problems with delivery.

Excuse me?! First of all, I’m no member of any „team“, and secondly, I’m not in the business, and have no intention of selling you anything.

Do I understand correctly you’re offering a free sample for demo e.g. among audiophiles here in Switzerland and nearby Liechtenstein, to be returned at no cost if we find it does not back up your claims of superior sound quality?

If so, and you stand behind your claim, feel free to PM anytime! The very least you can expect is fair feedback, needless to say, if your product is indeed better sounding than the ones we discussed, I’ll buy the demo unit.

In addition, I’ll see to it that @christoph and @morricab would get to demo your product in their respective systems.

No thx I can quite well read a tube data sheet.

I might add to get around 45 watts of single ended power…from a single tube you need about 3x the dissipation of the 811…like a GM70, which has 125 watts max dissipation vs. 45 watts for the 811a. Did you by chance mean two 811as in parallel to make 45 watts? I still find that hard to believe…

Yes and an 833 over 140 watts
