Powered speakers show audiophiles are confused

@thespeakerdude

I am not up on all the latest in home audio equipment to even begin to spend $200K,

+1 (+10!)🤣

@donavabdear

Please start a build thread so we can get started, it should be a great thread when you see how many ideas you get from other members. I have some things I feel are KEY before you do anything. You have a dual space and if you get the mixing space wrong it will not only cost you budget, it will cost you income! See you in the new thread when you are ready but I recommend scoring that amp ASAP.

I admit my limitations as opposed to doing no research and recommending an out of production amplifier not suited to the system. Run that amp in the constant current mode and you would add new +/- 3db peaks/valleys to the frequency response that are not currently there

@donavabdear , creating a separate topic makes sense. Are you planning to add room correction to this system, or just keep it the way it is?

@donavabdear ,

Clearly someone in this thread is out of ideas so is attacking the messenger here.

If you want toob goodness from solid state this is the best alternative I know. I have tried many Sunfire products (preamps, subs and amps) and can assure you it will be a quality experience. Whether or not it is "tooby" enough only you can tell. 

Re, the 7401:

 "...TGA-7401 is one of the most powerful multichannel amplifiers. The whole index of the device stands as follows: Theater Grand Amplifier 7 x 400 watts. Such return became possible due to quite clever system of tracking supply (patented by Bob under the brand Tracking Downcoverter). The idea is simple: in a common amplifier a high potential of power is constantly applied to output transistors, but in Carver's amplifier it changes in such a way that voltage allowance in reference to amplified signal is always 6V. But the realization of this principle is quite difficult because tracking must be performed with high accuracy and speed - a separate pulsed system answers for it. Carver created the amplifier, which almost can't be forced into clipping (our power supply had up to 800W on 47 Ohm), as output transistors always work in optimal and safe mode. The idea - "complex load" - doesn't exist for TGA-7401: actually it adjusts to any. In addition, lots of energy is saved, which went into heat before. " The inefficiency of conventional amplifiers results in accommodating the wasteful appetite by relying on massive transformers and other over-building to achieve about the same results, at more expense - and they really are limited by their thirst for more continuous power than any 15 or 20 amp circuit can provide. Read up on the patented Tracking Downconverter. Not only that, but a 20 amp power supply produces 2,400 continuous watts, and can produce several times that for very short times, though many times the length of musical notes. The patented Tracking Downconverter takes full advantage of this phenomenon, and is the only design that does. Another advantage is the Tracking Downconverter allows significantly lower continuous consumption of power, which is reflected not only in saving money on the amp itself, but also saving on the power bill, and therefor being a far more Green product through an advanced technology.

Thank you guys I admire both of you, you come at the problems from different perspectives. 

My BHK 300 amps have tube input stages and Mofset outputs that's the way it should be tube output stages is the weakest part of tube amps, tube amps with very few exceptions are underpowered but what they have going for them is the distortion sounds wonderful. Also if you use the equipment a lot the tubes only last about a year, and degrade from day 1, I'm really tired of it. I think a new build thread seems like a fun idea. I do have that Lyngdorf processor and I'm going to put it back in my home system without the PS Audio preamp and DAC. All outputs are balanced, I just took out a JL Audio CR1 which is an interesting unit that divides the low frequency to optimize for stereo and home theater, but with the Lyngdorf I can program all that. The PS audio equipment is surprisingly good for the money I have all top of the line equipment from them but I've heard more expensive systems that were not nearly as good as mine. Every time I listen to a SS system I think tubes would sound better, there is just a warmth that feels so good at the end of the day. I think I might look at some of the better systems in this group and copy theirs, I really don't want to have a bunch of equipment that is not designed to go together. Steinway is the only company I can find that designed everything together, but it so expensive no one has it and a few people who know say it way over priced, no one says it doesn't sound good. Thanks

Meridian is a company that takes designing things to go together to a completely other level. I have heard their gear (not recommending you change) and while expensive, it sounds great and is absolutely worth it IMO. In a thread on active speakers Meridian is up their with the best for my taste.

I look forward to your new thread.
