Expand your listening horizons with the black A-S501 Integrated Amplifier from Yamaha . Featuring up to 100W per channel of RMS power at 6 ohms, this amp is equipped with digital inputs for connecting devices like televisions and Blu-ray/DVD players. It offers dual stereo outputs, giving you the ability to power two sets of speakers in different rooms and switch between them, or have them both playing at the same time. To increase the bass output of your sound system, there's also a terminal for connecting a subwoofer.
To reduce distortion and degradation and produce the cleanest possible sound, the A-S501 employs Pure Direct Mode. Activated via a button on the front of the unit, this mode causes input signals to bypass unused circuits and cuts off those circuits' power supply. To further ensure quality sound, the amplifier's continuously variable loudness control allows you to balance low and high frequency sounds so you can hear a full tonal range at any volume.
This Yamaha amplifier was built with energy efficiency in mind, and uses a power management system to switch itself to idle mode when not in use. The A-S501's internal circuitry mirrors itself symmetrically to produce higher signal purity and lower degradation. The chassis is reinforced with a solid center bar to reduce vibration and features a brushed aluminum front panel and knobs. The system comes with a remote control for easy operation.
- Pure Direct Mode
- The Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.
- Continuously Variable Loudness Control
- The A-S501 features an analog loudness control on the front panel, which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low- and high-frequency sounds, providing full tonal range at any volume level, compensating for the natural loss in the human ear of high and low frequencies at soft levels.
- Direct Symmetrical Design
- This amplifier's left and right channels are organized in a straight, symmetrical layout for limiting distortion and increasing signal purity.
- Anti-Resonance Chassis
- The base of the A-S501's chassis is reinforced with a solid center bar to increase rigidity support and vibration damping, which limits resonance.
- Dual System Capable
- You can connect two separate speaker systems in different rooms and switch between them or have them both play at the same time by switching the dial on the front of the unit.
- Phono MM Terminal
- You can connect a turntable with an MM phono cartridge to play vinyl records, allowing you to enjoy records in addition to modern media sources.
- Auto Power Standby Function
- This amplifier puts itself into standby mode when it detects that it hasn't been used in approximately 8 hours, minimizing power consumption.
- Remote Control
- Control your music from afar with the included remote, finished to match the design of the amplifier. The remote comes with batteries and can also be used to control a Yamaha CD player.
- Connection for Bluetooth Wireless Adapter
- With the optional YBA-11 Bluetooth Wireless Adapter, you'll be able to stream music wirelessly from a Bluetooth capable mobile phone or a PC to the network receiver. This amplifier features a DC-out connection on the rear panel to power the adapter.
- Rotary Encoder Input Selector
- The rotary encoder makes it quick and easy to select input sources, and the LEDs clearly show which source is selected so you can easily switch between them, even in a dark room.

Works well, but is now too expensive...
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
The "No added sweeteners" has been my go-to version of Metamucil, but I'm giving it 4 stars and moving on to another brand as the price is over $35 which is too much imo...

Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I like the mildly tart taste of this unflavored, unsweetened drink made up with water. The texture doesn't bother me, with stirring right from the beginning of adding the water, there is no clumping. After 10 days there is no effect on my bowels which were regular previously anyway. My doctor wanted me to use this although I already have a high fiber diet.

Definitely Not Unflavored. This is Tart / Sour, Which Limits the Options to Certain Juices
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was expecting an unflavored fiber powder. However, expect a sour/tart taste. This means you can't add it to tea or coffee. I don't think it is appropriate to say that it is "unflavored" as I've had psyllium husk from other vendors that are truly "unflavored" (i.e. no citric acid). Dextrin (another fiber source) is also unflavored. But this Metamucil is tart (like sucking a lime) and can only be added to tart juices like orange juice or lemonade.

Happy it is unflavored
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was worried about the taste based on some of the reviews. I tried it in my coffee, and I'm glad I did it that way. I keep coffee in the fridge, so that is what I mixed with one tablespoon of this. I use half and half and no sugar. I tasted it. It tastes like burnt coffee. Not a bad thing...thats just what the taste it added. I decided to see what would happen if I added a splash of a flavored creamer. The taste went away instantly. Hope this helps someone!

Purchase or perish.
Format: Paperback, Format: Paperback
I don't think Mike can produce anything below 5 stars. In his recent Christmas episode on the Naked Bible Podcast I was a bit wary of listening to it. I realize this is a review of his book here, but let me make my point. The problem with not wanting to listen to his Christmas episode is that I don't really care if Christmas was/is a pagan holiday. So, honestly, it wasn't appealing to me. Somehow I ended up listening to it, and I'm telling you the amount of information he crammed in there was FASCINATING. I'm not kidding. I was so tired of hearing that subject (because I've been born and raised into Christianity), but Mike and Trey did their thing and it had me on the edge of my metaphorical seat the entire time. If you listen to that episode (Naked Bible Episode 195) you'll see exactly what I'm talking about. And what's the point of all that I just said? It's that Mike doesn't do anything half way. All that he puts out is serious work that is worthy of much consideration. No Hillary v. Trump fact checking here (though I'm sure he'd encourage you to research what he's saying). The point is, however, that not everyone has the training that he or his contemporaries have. And THAT is exactly why it is paramount that we rely upon scholars who have said extensive training.
I challenge you with this (something I've challenged myself to accept): You essentially know nothing about the Bible if you don't have not just Heiser's background, but other scholars such as John H. Walton. There are many to list, but Walton would be a good companion to list next to Heiser. If you're the lay-person, do yourself a favor and pick up this work, or The Unseen Realm (or both!) and any of Walton's work. Open up your mind and challenge yourself to realize that unless you are incredibly familiar with the Ancient Near East's way of life and thought processes, then it's highly likely that you don't actually understand what is going on when you read the Bible.
Enter "The Bible Unfiltered."
Considerations for the seminary student:
This is a great book for those who need a quick reference on a particular subject. Heiser's name is well known, and thus to reference this book in one's papers, even for a one-liner, is to reference legitimate scholarship. I'm not advocating that one does one's entire paper off of just one chapter from this book, but my point is more-so that with Heiser's reputation it will be known that you're not quoting Joe Scholar who earned his PhD in I Do What I Want. If you know Mike then you know that he's done a lot of work to present to you CONTEXTUAL research on any given listed topic. For that alone the price is worth it (though it undoubtedly cost him more to do the research that it does for us to purchase the book).
Considerations for the lay-person:
1. On p. 7, Heiser says, "If Bible study doesn't seem like work to you, you aren't really doing it." Yes, that's harsh, but so was Phinehas, Peter, Paul, and Jesus. (Even Bonhoeffer was harsh in his "The Cost of Discipleship")! Over and over again Heiser says on his podcast that Bible reading is not actually Bible STUDY (not yelling, I just don't have italics in this comment box).
2. This book is great for having a quick reference for subjects. You do not have to read the book in order to understand the content of any given chapter. I use this book to help direct me to other scriptures that I can't seem to remember. Here, Heiser treats topics with brevity, yet with depth at the same time--depth that stems from years of immersing hisself in the original cultural context, the surrounding culture's contexts, and original languages of the Bible. In other words, this book will act, for the lay person, as an appetizer that gets you excited for the full meal and subsequently spark a desire within you to finally take seriously contextual Bible study. If you've never read Heiser's stuff before, this is a great place for you to get introduced to his work. From here I'd recommend getting The Unseen Realm, and then Reversing Hermon. Follow all his other works at drmsh.com, nakedbiblepodcast.com, and moreunseenrealm.com (I'm not getting paid to say all of this).
Considerations for the scholar:
Rid yourself of your presuppositions, get with the times, and adopt the supernatural worldview of the Bible's authors, because yours isn't supernatural enough. (Can that be considered speaking the truth in love?...)
(Pictures won't rotate for some reason. Sorry!). My hand on the book next to the Schuyler Bible shows the size of the book.
