Monitor 10

Welcome to the forum. Congrats on your new to you speakers. There are many here that own/have the monitor 10. I've had & enjoyed many HK receivers & liked them all. Great choice. We have members here who knows more that i know when it comes to that model @mhardy6647. Welcome again. Randy, Maine USA..

I used an HK 730 with my Monitor 7As and agree with the recommendation. I think any of the high current twin HK models (430,630, 730, 930 twin) are know well, but the there .

The SL2000 tweeters are known to be a little bit harsh, so replacing them with the RDO194s is always highly recommended .

Unless you already have the 330 I would try to acquire a twin powered model, especially with larger room. I’ve heard some don’t think the 330 had any balls. One thing I didn’t like about the HK670 was the speaker binding posts which were fortunately changed out to five way binding posts. Those spring type binding posts are not my cup of tea. But the 670 was the flagship model I believe when new and sounds great. The 730 and 930 are by all accounts also very nice and they are all really good bang for the buck. The better the power the better those M10’s will sound. The RDO-0194’s will also make a good improvement as mentioned.

A 330c will sound very good with the Monitor 10 (at least the earlier morphs... I cannot vouch for the "10B" version). The 330c was commonly found paired with the less-sensitive (albeit slightly higher impedance) Monitor 7 models in the '70s; JHU's dorms were full of 'em back in those days, and they sounded fine.

The "twin power" hk models should be better, but the cost would be ​commensurately higher (then or now). The hk430, e.g., though only marginally more powerful (5 wpc = 1 dB increase in power per channel), was considered to be substantially ballsier ahem more cojone-enabled than the 330c.




Good modern amplification probably makes more sense in terms of cost, performance, and condition (longevity). Any 40-plus year old hardware will require substantial (expensive) rehabilitation* and/or have a questionable lifespan at this late date. And mind you, I speak as someone who loves the stuff.

* If it's been properly and appropriately rehabbed, the cost will be 1) not insignificant and 2) baked into the purchase price. If not, the time and expense of proper rehab must be factored into a purchase decision for 1970s or 80s hifi components!

I mean, I'd always suggest Yamaha... but that's me all over.

Sounds good, still reasonably well made, and reasonably priced.
I am thinking specifically of their two-channel integrated amplifiers.
