## Questions & Answers

**Q: Im finding the bass to be very heavy even with my bass turned down to lowest on amp is there anythinf that can be done?**
A: Dear, the YAQIN MS23B is a phono amplifier. Please feel free to contact us if you have any other problems.

**Q: I use two different headshells/cartridges  - one MC, one MM.   Is there an MM/MC switch on this unit?  If not, how does it handle the different carts?**
A: This preamp only works with MM cartridges, there is insufficient gain to amplify a MC

**Q: Hi what about replacement valves? how and where can i get them? how long will they roughly last? regards joe**
A: I purchased 2 valves which vastly improved the sound quality of the pre amp As I had to return the pre amp for a fault  I kept the valves I purchased so they are available to you if you would like them .let me know.   Email is ruffandready 2016@gmail.com cheers. Kev

**Q: I just reconnected this after about 6 months in storage and the sound is quiet, almost as if I'm not using a pre-amp at all. Help!**
A: I would check everything thoroughly, has it been correctly connected from the pickup and to the power amp?  The phono leads are all good connections.  Have the vacuum tubes been displaced from their holders, unlikely as they are well protected but worth a check.  Check your power amp is that working ok on other inputs? check fuses, you will need to open the unit up to do this.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Superb value for money
*by G***C on 6 February 2017*

I bought this phono amp as I was using the phono stage on an exposure vx11 preamp. The exposure is about 30 years old but still sounds fantastic. The unit is a full size box however and I wanted something more up to date and small and funky. I have a little dot 2 headphone amp so love the valve sound and looks. Ordered the Yaqin and it arrived very quickly and in mint condition - packaging was decent which prevented any damage to what I thought would be a fragile unit. No need to worry however. The unit looks great when unpacked and it sits nicely alongside the little dot. Only slight criticism would be the intensity of the blue LED power indicator light which is a wee bit too bright however the unit looks crisp and modern. Was a bit nervy about the sound - had I wasted my money, after all I had a very decent phono amp in the Exposure and was the Yaqin going to be any good in comparison. I was very happy to discover that this was a fantastic little amp. I listened using the stock tubes for a while and although it wasn't as good as the exposure it wasn't that far off - the exposure was a very expensive amp in its day and remember the Yaqin is budget price in comparison. With the stock tubes the sound could be described as a very smooth and detailed midrange , decent top end but a pretty wooden sounding bass end although I have heard much worse bass lines from other kit. I quickly ordered some mullard copy groove tubes from Watford valves which set me back about £55 or so. They are now running in and starting to sound sweet. Did they make a difference - you bet ! The sound has much more bite and the bass end is now much tighter and has the correct timbre in fact pretty close to the exposure. For a total outlay of just over £200 I am delighted with this purchase after all a good phono amp is normally prohibitively expensive - not this little beauty ! Not sure how good it would have got with the stock tubes as I didn't run them in for too long and I am sure a lot of people would be more than happy with them if on a budget as they still sound very decent. Glad I went for the upgrade tubes though. If you have a good record deck and cartridge - Linn, Systemdek, Thorens or Michell or the like with a MOVING MAGNET cartridge do not hesitate to buy this as it won't be out of its depth - beware though MM only no MC input.

### ⭐⭐⭐⭐⭐ A real performer.
*by J***L on 4 March 2017*

I bought it with some reserves as I thought "real Hi-Fi made in China? but it has proved me wrong, the Yaqin MS23B phono pre amp is a real performer. It sounds like night and day over the built in phono input on my Pioneer SC LX-76 A/V receiver (which was 2000€), the yaqin just sounds better. It get the most our my cart (Denon's DL160) and the grooves of my vinyl record. Where the integrated phono pre on my receiver sounds just OK, it turns out that next to the Yaqin MS23B it sounds muddy, dull and lifeless. The Yaqin bring music alive, it reveals details I couldn't get before. At the same time it sounds like a blend of neutral and sweet, I think it has to do with the two triodes CC83 valves it uses. Bass get a "boost" without sounding boomy, I guess the Yaqin is revealing what's just on the record's grooves, mids have real presence and highs sound silky but have real presence in the sound. It never sounds thing nor bright.The Yaqin MS23B is great with the valves it comes from the factory, but changing the CC83 valves to a pair of Gold Lion's CC83 with golden pins (which are not cheap but can be found for a reasonable price on the net) made it OUSTANDING.I'd buy it again, the Yaqin MS23B is a real performer.

### ⭐ Fault product, but there's no way to contact the seller?
*by T***A on 15 February 2019*

I bought less than 3 months ago and noticed that the left channel is much quieter than the right channel. I've recorded the same record with using this pre-amp and other pre-amp and result was so clear that you can see on the sound wave. I'd like to discuss the potential solution for the seller, but i can't find anywhere to contact. Please contact me directly if you are seller and willing to find the solution with me. Thanks
