What's your process for replacing a component? What if you buy something new and don't like it after comparing? Are you able to return the new purchase?
Honestly, most changes occur swiftly and often on a whim. It's my opinion that any decent dealer should allow home auditions for serious clients. They can instantly identify those clients and separate them from the ones that will ultimately be a waste of time for one reason or another. Building relationships with dealers certainly helps. I've made many connections over the years. I guess it comes down to how hardcore you are; with one dealer in particular, I just text message the owner directly. One thing that really annoys me are the super uptight snobbish dealers that can be almost disrespectful to potential shoppers that fall outside of their preconceived notions of "what" their customer should be - big tymers. Often times that type of dealer all but alienate the overwhelming majority of buyers by offering almost entirely the most esoteric upper echelons brands. They're too caught up in selling an image and bling. In contrast one of my absolute favorite dealers to interact with is really down to earth and loves to rock out to Dio.

That dude runs his shop for the right reason, the enjoyment of music.
I've only had one instance where I was really disappointed with a deal and returned an item. It was as much about being disappointed with the dealer as anything. I had to rely on them as they were out of state; this particular item has somewhat limited distribution channels. They accepted the return several weeks after I had taken delivery. We ended up working out a swap. I don't wish to name any dealers or products. It was a somewhat elaborate turntable that I made some specific custom configuration requests on. Overall, it a real pain moving around 60 pounds worth of turntable.
You never really know how any component will truly work out until it's in your in your setup. After being fairly dedicated to the hobby for so long, I learned a lot about what just works. Making a total wrong turn isn't a real concern at this point for me. I have plenty of stuff on hand for comparison. There are setups in the living room, master bedroom, my dedicated room, on and off again vintage system, and my wife even have a small little separate setup just for her use. Then there's all the stuff in closets.
I'm still quite interested in pursuing a low watt set up at some point; any new & or additional takes on it?
Thanks in advance!
It's a cool path to go down for sure. Like I said, there's no right or wrong as long as it gives you the music enjoyment you're seeking. I find a lot of positive attributes to the simplicity of design that is often utilized in this product category. Often times the components and speakers take minimalist approach. There's certainly something to be said regarding less can be more. Getting high efficiency speakers is a must. I feel fairly strongly that a tube based system is really the best way to go. If that's something you're not interested, I'd suggest the gear by First Watt. I have not personally used First Watt components. However, this is one of Nelson Pass's companies, and I'm very familiar with Pass Labs; excellent smooth sounding class A solid state. Getting back to tubes, one of my favorite, and affordable, manufacturers is Quicksilver. They have a pair of mono amps explicitly designed for high efficiency speakers. I had a pair of their recently discontinued, 25 watt, mini-mono's. Exceptional value for the price. All hand made in the US, with point to point wiring, and lots of options for tubes. They also make a pretty nice preamp for a very reasonable price. Decware is another maker of tube gear that has been around for a long time. Their products share the same positive attributes of the Quicksilvers, plus they provide a lifetime warranty to the original owner and the option to certify preowned gear purchased 2nd hand. Quicksilver is certainly something I hope to own again at some point; I can't say enough positive comments on these products. I haven't owned Decware, but did research it heavily, and came very...very....close to purchasing. Recently, Wolf Ear Audio has caught my attention, as I still keep tabs on world of flea watt amps. I don't have any firsthand experience and not a lot of info. But it does appear to be nicely made, in N. America, product that's gaining some traction.
Concerning speakers for this type of setup try to stick with a rating of around 95dB/1w/1m or higher, if plan to use a very low powered amp. Example 2 watt. Most people do not realize how little power is typically required for listening. Having owned amps with meters I know firsthand how little power is often required. For example, in my 12x14 dedicated room, using 90dB efficient speakers I would see peaks of just 1 watt; most of the time it was between 1/4 to 1/2 a watt. Some of the best systems I have experience have been low watt. I've had positive experiences with Klipsch Heresy III speaker; they sound great in the right all tube setup and are extremely efficient. Deals can be easily found online for discounted new in box pairs; obviously, preowned is even more affordable. Some Klipsch fans have a preference of the II over the III. The older version is super affordable. These are part of the Heritage line and should not be confused with their lower tier products; I'd defiantly own a pair. Another excellent option, if you want a more "exclusive" brand, is Tyler Acoustics. They have a model that is comparative to the Heresy III. I like the Tyler products. Great sound and craftsmanship. I met the owner of the company once at a hifi event; very laidback and a straight shooter. If you are strongly opposed to horns, Omega makes some very nice high efficiency full range single driver speakers that are devoid of a crossover. I have had multiple interactions with the owner/designer; they make in my opinion one of the best affordable speakers of this design type. Omega has some very affordable options. Some very good introductory information can be found on their website; well worth the read to get you up to speed on this sector of hifi.
There are several other combinations that I have auditioned that are more costly than what I have suggested. Not knowing your budget, I felt tossing those out there wasn't necessary. But feel free to ask and I'll share my experience and opinion on those product combinations.
If you have any super specific questions, feel free to drop me a PM.
