Vhex+ or AMB b24?

[jaymz168]

Hi all, loooong time lurker here considering an amp build. Looking for something in the 100-200W range for multiway floorstanders (Wharfedales at the moment, will be upgrading these fairly soon).

I've pretty much narrowed it down to a VHex+/NS Modular or an AMB beta 24, though other suggestions are welcome. The VHex+ seems like a good low-cost choice but I do lack SMD soldering experience and I'd have to source or design a PSU for it. AMB seems to have quite the following and a fully differential design is attractive, but the builds I've seen look like they're going to work out to significantly more than a VHex+, and the VHex+ actually has overcurrent protection, speaker protection, etc. while the AMB has none of this.

Thoughts?

I'm obviously biased, but the VHex assembly is quite easy to assemble. There's no reason to be intimidated by SMD parts. We have power supply boards available too. The VHex doesn't require anything special for a supply. It's got excellent PSSR built in. We soon hope to offer complete kits containing everything. Chassis, supply, protection, hardware, ect. Just assemble and enjoy.

I agree that VHEX+ build was very straightforward and SMD is not hard. These are very large SMD parts. Watch a few YouTube videos on how to solder and practice on a few. It goes faster than through hole because it's only on one side you work and there's no bending leads or trimming excess. I have tried with basic trafo and CRC but am using 53v Abletec SMPS very nicely.

Another plug for vzaudio. vzaichenko and jwilhelm are first rate. I have built a couple of their designs and am more then happy. Plus you can be sure of getting help if you need it.

Soldering smd is an easy work.Just a good solder tip and 0,5 mm solder wire.
Stable hand and good eyes or magnificent tools.

Yes, thin solder wire and tip are the two most important keys to success with SMD.

Check your PM and update me on your Symasui.

Thanks for the suggestions everyone! Re: SMD, I've been following an SMD soldering group on Facebook for a while now in preparation for building an ARP 2600 clone (TTSH) so I've gotta buck up and do it eventually!
