  • Peachtree Audio's Nova 220 SE integrated amp marries muscle and musicality

    Having thoroughly enjoyed Peachtree Audio's Decco 65 last year, we found ourselves eager to see what the company would bring to CES 2014. As it turns out, what it brought is just as hot as the Decco 65, but with a healthy dose of testosterone and a sprinkling of finesse. Like the Decco 65, the Nova 22o SE is an integrated amp -- there's no tuner, no video processing, and no complications. It's designed to reproduce stereo audio as cleanly and simply as possible, but, as the SE (special edition) badge implies, there's some special goodies under the hood. For starters, the Nova 220 SE packs 220 watts per channel into an 8-ohm load, but if you have lower impedance speakers, it will deliver up to 400 watts into a 4-ohm load. That's the brawn, but the beauty in the sound -- the detail and wa...

That's the brawn, but the beauty in the sound -- the detail and warmth that makes you feel all fuzzy inside when you hear it -- comes from the amp's Class-A pre-amp section with tube buffer stage. We heard the Nova 220 SE in action paired with a set of easily-driven Goldenear Triton Seven speakers as well as some notoriously difficult-to-drive Martin Logan Montis electrostatic speakers. In both cases, music reproduction sounded effortless. We're looking forward to getting a review sample in for a detailed look and listen. For now, enjoy how sexy this amp looks in action in our up-close video from Peachtree's Suite here at CES 2014.

Thank you for watching my Marshall MS-2 Micro Amp review. I hope you found it helpful. While I believe we covered a lot of the questions you may have in this video, I realize that there might still be some more details that you want to find out about the Marshall MS-2 Mini Amp. As mentioned in the video, I strongly encourage you to check out my comprehensive article review about this device which you can find on my website along with more details around features, FAQs, comparisons to other mini amps, pros and cons as well as purchasing information. http://guitaringenuity.com/the-marshall-ms2-micro-amp-review-functionality-features-and-sound/ If you are subscriber to my channel, you may probably know that I in the past did a few reviews on the popular Vox amplug mini guitar amps. People who watched those review asked me, if I could take the Marshall MS2 for a test ride and share my findings. Well, my wife must have used her sixth sense – she put this guitar accessory under the Christmas tree for me. Therefore, I was now able to test the MS2 amp for a little while and share now my findings and thoughts with you. To recap the main points I made in the video: The MS-2 by Marshall comes in different versions. First of all, there is a half-stack and a full-stack option. On top of that, you can get the device in black (standard), red (MS-2R) and chrome (MS-2C). The design is simple, just the way a like it. Instead of trying to cramp-in too many buttons and features, the Marshall did well by keeping the layout straight forward. Overall the casing is very solid and the thing looks really neat, in my opinion. There are three dials in the front of the Marshall MS2 mini guitar amp: Volume, Tone and Off/On/OD. Volume and Tone are self-explanatory. As for the last dial, it serves a dual purpose as the on/off switch as well as switching into overdrive mode. In the regular channel, the sound is decent, but it lacks volume. You need to bring up the volume to “5” or higher, but the problem is, the more volume you add the crunchier the sound gets. In the overdrive channel, the Marshall MS-2 mini amplifier kills! The tone is awesome. Playing around with the Tone dial gives you a broad spectrum of sound, anything from ultra gainy to doomy. Instead of using the integrated speaker, you can connect a headphone set. Also, the device can be powered either via a 9V DC Adapter which you would need to purchase separately, of a 9V block battery, which comes with the product. The battery life is very good, but you need to ensure that you switch off the MS-2 after you’re done playing! The Marshall MS-2 is a lightweight at 12 ounces. Oh, yes, you can absolutely use your pedals in connection with the MS-2. It works very well, I tried it myself. Also, instead of a regular guitar, you can connect a bass guitar. Alright, let’s wrap this up: In my personal opinion, the Marshall MS-2 Micro Guitar Amp is a great product at a very reasonable price. I love the fact that it has an integrated speaker, so you don’t need a headset, yet you can use one, whenever you want. The sound quality is better than I expected. Yes, I wish the clean channel could produce more volume, but that’s okay since I’m playing in overdrive most of the time anyway. The design is slick and the overall quality to the Marshall MS 2 is great. So, what do you think? Any more questions for me? Fire away and leave them in the comment box below. Don’t forget to check out my article with more details on the Marshall MS-2 micro amp. Thanks for watching.

This is a no-frills educational Class A solid state amp, based on a single NPN transistor as an amplification device. Last year I tried to do this as an exercise, but I found that finding out the exact resistor values suitable for this application is a huge ordeal, which Google helps with just about nothing. There are literally *THOUSANDS* of webpages, which discuss the basics of class A amplification, but the given schematics show the topology only; none give precise resistance/capacitance values, and after a few hours of aggravation, I moved on to something more fun. However, a while ago I stumbled upon a very useful (at least for noobs like me, that is) circuit simulation applet at http://www.falstad.com/circuit/ . This was just what I needed to complete this toy project - indeed, it worked right out, as soon as I laid down the last element on the breadboard! So, to fill the gaping hole in the internet w.r.t. Class-A-no-frills-9-volt-amps, here are the schematics of my amp: http://anrieff.net/abs/i/class-a-1.png A few notes: * You probably saw the second transistor and shouted out *YOU BLOODY CHEATER!!!*. Indeed, there is one, but it does not take part in the amplification - it replaces the 0.47 ohm resistor in the above schematic with a controllable resistance (just because sub-ohm pots could be problematic to find, you know :)). The actual schematic of the thing shown in the video is here: http://anrieff.net/abs/i/class-a-2.png * The element I'm abusing later is the 10 ohm resistor, which is grossly underspec'ed. It should be a 5W part, but I only had a 2W one. It survives, however, probably because of the "Сделано в СССР" factor. In fact, it should endure for at least 15 minutes, which is fine, as the battery drains out in ~10 :) * The battery in the clip is nearly dead, but with a fresh one, and at optimal conditions, the amp consumes around 3.5 watts, and it puts out only about 0.3W! This is just about sufficient for normal listening in a small room.
