Coincident speakers 14 Ohms - What amplification to use when streaming Tidal.

The Coincident  SET amps are quite reasonable.  I would ask member charles1dad, he is using their amps.

You can certainly use a tube amp in a streaming setup. And you may want to look at pushpull rather than SET amps depending on your budget. SET amps really need a great output transformer and those cost money. There are good budget pushpull amps not so many budget SET amps.

Your speakers are made to be used with very low power amps like SETs.  I don't know if you would enjoy that sound more than what you've got.

If atmasphere doesn't chime in I would message him.  He is a proponent of high sensitivity/high impedance speakers.

Not sure if I follow the connection...

I used to own Victory II’s. With the rear ports, they were a little tricky to place in my small-ish room. Salvatore wrote that they can be an exercise in frustration if not fed quality components. That said, I found that they are capable speakers with many different types of amps. It will come down to a matter of taste. I tried 5 different amplifier topologies with mine. My personal favorites were my 8 watt SET monoblocks (that I still own), and an 80 watt OTL amp (that I ended up selling because they generated too much heat). I felt the sound with these amps was more fleshed out and more immediate, at least to my ears, than the other amps I had at hand. The other amps were push-pull 300B, A/B solid state, and EL34. They all sounded good too, just a bit thin and less "you are there" compared to the other two amps, IMO..

Thank you for all these knowledgable responses.  I need to inform all that I am a bit stuck in 1976 regarding audio components, and I am not very well versed anymore.  My budget for everything would be about $2000.  The speakers will be placed in a large, open concept living space, approximately 1000 square feet.  I am not a true audiophile anymore, due to multiple moves (7) in the past ten years, making my collection of Parasound, Myryad, and Roksan amps moot.  Now, I use a simple sound bar for the TV, and I just want my own space in this current rented townhouse for my jazz listening pleasure.  Streaming music makes life easier, and we will be moving again. I am cognitively deficient in digital anything. Thus, I want to use my Coincidents, stream from Tidal, with the least hassle imaginable.  Move a few times and you will understand.  All I know is this:
I need a DAC
I shouldn’t be using Bluetooth 
The 14 Ohm speakers create a problem
A Bluesound Node 2i was recommended
I want to spend a total of $2000
These speakers may need a subwoofer and my Vredestein may be too powerful.
I am at a loss and need help.  Audio has gone way beyond the days I took my Marantz amp, tuner, and preamp and hooked them up to my EPI speakers and Gerard turntable.  It was so easy back then.  Thanks for any advice.  I do feel very old.

That was a Garrard turntable.  See what I mean? 

And now that I’m remembering, the amps were Macintosh 

The 14 ohms impedance isn't problematic for any amp.

It does not matter what source you use or what music you prefer. But you will need a bit of power since your music room is a bit bigger. So the SET idea is right out (and FWIW, most of the Coincident line is a bit on the low side efficiency-wise to really show off most SETs). The speakers are an ideal match with our M-60s, but they are outside of the stated budget. For that sort of money I'd be looking at something used with at least 60 watts.

You might consider line magnetic. There are a few models listed at usaudiomart that would be interesting to me if I were in your situation (I had super eclipse and now have pure reference extremes).

Decware might also be an option. I'd be biased towards tubes, although I did end up at first watt with my pre's. Loved coincident Frankensteins with the SEIIIs (move than a sit2).

Thanks.  I will check those out. My Coincidents are at a 97 db sensitivity, so I don’t think that is inefficient, but what do I know.  Seriously, using an 8 Ohm amp on these 14 Ohm speakers will cause what kinds of problems?

Yes- at that impedance 97 dB would be a high sensitivity. In practice though it appears that the speaker is more like about 94. Using the 8 ohm tap will be no worries.

That amp would sound fine, but if you plan to fill 1000 sq feet(!) you'll need considerably more power unless you will be fairly close to the system.

Same here... how are the two connected?  Pick an amp you like and that interfaces well to your speakers.  In the end streaming and vinyl are both 1V nominal analog music signals

The Bluesound Node 2i would work for your streaming source.  It's really easy to set up and use.  It can connect with your  WiFi router either by WiFi or ethernet cable.  You download an app to your phone or tablet and control it with that.  If you have any problems someone here could advise you on where you're going wrong.

I don't know what the difference between the Node 2 and 2i is but you can probably pick up a 2 used here, if you want to save a little there.

A Bakoon SCA 7511 integrated amp should match well.They are solid state class A/B but current drive,have zero negative feedback and like SETs have a high output impedance .They do not sound exactly like a SET but are probably more like them than any other SS amp I have heard.Only 15 watts but an absolute quality 15 watts and  if your speakers suit are capable of extremely high end sound and are very affordable.

97 (or even 94) dB sensitivity is VERY efficient.  Compared to a typical 89dB speaker that means you need something like 1/4 to 1/8 the power for the same volume. 

An "8 ohm" amp is simply the load it is rated into.  Ohms are a measure of resistance. The higher the easier to drive. The lower the harder. Zero ohms is a short circuit. In practice nearly every amp (except tube amps) is designed for a s low an output impedance as possible -- on the order of 1/4 ohm (0.25 and below). Its the other way around that's a problem - a high impedance output tube amp cannot deliver high current.  A 4 ohm or  (yikes) 2 ohm speaker demands lots of current.  No go, like an under powered motor.
The good news is that at 97 dB it wont need much current anyway!(for the record current = voltage / load in ohms).
Bottom line a really good solid state amp ought to dive anything. Within reason mine will.

97 (or even 94) dB sensitivity is VERY efficient.

I would characterize 97 as the high end of moderate efficiency and 94 in the median of moderate, with 90 at the bottom. 89dB this at the higher end of low efficiency, and 97-98dB at the lower end of higher efficiency as there are speakers that are 107dB 1 watt/1meter...

just some data points for respected hgih end speakers:
Vandersteen 2 - 90dbTotem 88dbMaggie 7s 86 dbVienna mozart 90db

are there speaker at 107? Probably.  But its rare and suggests it was optimized for other than sound

are there speaker at 107? Probably.

Such will be horn-loaded. The Hartstfield loudspeaker, which uses JBL components, is quite respected and is 105dB.

Thanks for all your help.  The knowledge displayed on Audiogon is way beyond my modest intellectual abilities.  I do love music though, and I know when equipment is providing a musical experience that transports. That is a special, transcendental moment.  That is why, with my audiophile desire contradicted by my handicapped knowledge base, I need the input of the audigon community.  I thank you and please keep the suggestions coming.
