Ultra-High Performance NFCA Modules
Adopting the same NFCA module with A90, TOPPING L70 utilizes a voltage current hybrid feedback architecture along with UHGF(Ultra High Gain Feedback) technology to provide excellent DC and AC performance，ultra-low THD+N and absurdly high dynamic range of 146dB. Even more, high output current drive capability, ultra-low output impedance and the ultra-low noise of 0.3uV which is miles ahead of the competition provide sufficient guarantee for driving headphones with various characteristics, so that high-fidelity music can be vividly performed on different headphones.
12V Trigger interface
The L70 is equipped with 12V Trigger in & out interface. With only one easy-to-obtain 3.5mm to 3.5mm cable, the L70 can be turned on and off synchronously with other devices equipped with a 12V Trigger interface.
Powerful Output Ports with Low Noise and Low Impedance
Compatible with almost all kinds of headphones, TOPPING L70 features high output voltage, high output current, low noise, and low output impedance. In this case, high output voltage can easily drive high impedance headphones. High output current allows low-sensitivity headphones to obtain enough power. Low noise allows high-sensitivity IEMs to not suffer from any background noise. The low output impedance will not bring unnecessary effect on FR when driving low-impedance headphones. It is worth mentioning that different headphones can be easily driven by the L70.
Dual Gain Setting Options
L70 features two gain settings to meet the needs of different headphones from low-sensitivity full-sized over-ears to high-sensitivity IEMs. With the help of extremely low noise 0.3uV, even IEMs will not hear any background noise.
Customize volume control
L70 utilizes a R2R volume control composed of relays and resistor networks, bringing the advantages of precise control, longevity, complete channel balanced and remote control. L70 can also memorize the volume and gain for eight output settings. This device can be adapted more personalized when connecting different earphones and other devices, which greatly improves the convenience of use.

Shipping FAQ
Which countries do you ship to?
We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.
We cannot ship to addresses that are "PO boxes or APO/FPO".
*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.
How much does shipping cost?
We have two shipping methods - Standard Shipping and Express Shipping.
Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 270USD, Express Shipping is free*.
*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.
Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the two-way freight charges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.
Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes. No refund will be processed for such cases.
Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Linsoul will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.
For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments.
Please contact us before placing an order, should you have any queries regarding shipping.
How long does it take to receive the order after it is placed?
For in-stock products, your order will be shipped within 3 working days. You may check with our staff regarding the in-stock status of any products.
Customized items will take a longer time. Please contact our staff for more information.
On normal non-sale days, once your parcel has been shipped out:
- For Standard Shipping, it takes about 2-4 weeks for items to be delivered after shipping out. For some countries, it might take up to 2-3 months, depending on your country, its customs and other factors.* The duration for transit is something beyond our control. Linsoul will not be making refunds for such cases. Please consider an upgrade to Express Shipping or keep the waiting time in mind.
- For Express Shipping, it takes about 3-7 days for items to be delivered after shipping out.
*Note: Timings might be affected due to festive seasons or other unforeseen circumstances
What happens if the parcel has been shipped but not delivered?
- First, kindly contact your local courier using the local tracking number.
If your parcel were to be in transit for at least 3 months, it may have been lost in transit.
For orders below $50USD, you may either opt for a one-time reshipment of parcel OR a full refund of the amount paid in cash via PayPal/Credit/Debit card.
For orders above $50USD, we will only process a 50% refund of your order paid in cash via PayPal/Credit/Debit card. Should there be any concern about Standard Shipping, you are encouraged to opt for DHL Express Shipping instead. - Customers are to bear the consequences and fees incurred, if the parcel was undelivered due to any of the following situation:
- Wrong address or phone number provided by recipient
- Recipient was uncontactable when courier company contacted
- Refusal to sign for the package by recipient
- Lost or damaged parcel because recipient opted for “no-signature delivery”
- Refusal to pay for the local tax/processing fee by recipient
- Refusal to provide supporting documents for custom clearance by recipient
Who will pay for the import tax/custom fees
Customers have to bear any form of custom/import/processing fees that are applicable for your parcel.
Should you be unwilling to pay for the fees and reject the delivery of the parcel, you will still have to pay for the shipping cost. Linsoul will only refund the amount of your order after deducting the two-way shipping fees incurred.
